“One of the most important of these ceremonial functions is called Urja-vrata. Urja-vrata is observed in the month of Karttika (October-November); especially in Vrndavana, there is a specific program for temple worship of the Lord in His Damodara form. “Damodara” refers to Krsna’s being bound with rope by His mother, Yasoda. It is said that just as Lord Damodara is very dear to His devotees, so the month known as Damodara or Karttika is also very dear to them.
“The execution of devotional service during Urja-vrata in the month of Karttika is especially recommended to be performed at Mathura. This system is still followed by many devotees. They go to Mathura or Vrndavana and stay there during the month of Karttika specifically to perform devotional services during this period. In the Padma Purana it is said, “The Lord may offer liberation or material happiness to a devotee, but after some devotional service has been executed, particularly in Mathura during the month of Karttika, the devotees want only to attain pure devotional service unto the Lord.” The purport is that the Lord does not award devotional service to ordinary persons who are not serious about it. But even such unserious persons who execute devotional service according to the regulative principles during the month of Karttika, and within the jurisdiction of Mathura in India, are very easily awarded the Lord’s personal service.” (Srila Prabhupada in NOD chap. 12)
durlabho bhakti-yogo me mama vasya-vidhayakah

“Pure devotional service to Me which, because it places Me under My devotee’s dominion, is very difficult to attain, is easily attained by following this vow in Mathura during Karttika.”
“To they who worship Krishna in Vrindavan, the Lord gives them their original spiritual forms. The perfect atonement to purify the sins of a lifetime is to worship Lord Damodara in Vrindavan during Kartik. The month of Kartik spent in Vrindavan brings the supreme destination.” -Srila Rupa Goswami, Mathura Mahatyam
“In the month of Kartik, which is very dear to Sri Hari, one who bathes early in the morning attains the merit of bathing in all places of pilgrimage. Anybody who offers the Lord a ghee lamp in the month of Kartik, O brahmana, becomes free from all kinds of sins, such as killing a brahmana, and he goes to the abode of Lord Hari.” (Brahma Khanda).
As Satya-yuga is the best of yugas, as the Vedas are the best of scriptures, as Ganga is the best of rivers, so Karttika is the best of months, the most dear to Lord Krsna - Skanda Purana
“Suta Goswami says, “If anyone fasts and observes the Kartik-vrata according to the rules and regulations, the Yamadutas, the messengers of Yamaraja, run away from him, just as an elephant runs away by seeing a lion. This dear fast [vrata] of Lord Vishnu is even better than performing one hundred great sacrifices that would take him to heaven because the person who observes the Kartik-vrata goes to the spiritual world.” (Padma Purana)
“Although one can easily reach Mathura [Vraja Mandala] on this earth, and although Kartik month is easily observable, and although in the month of Kartik all of the places of pilgrimage, oceans, rivers, and lakes come to the Mathura area, still, those human beings who are foolish and suffering in the ocean of material existence do not take advantage of it.” (Padma Purana)
Kartik is the best, the purest of purifiers, and most glorious of all months. Kartik month is particularly dear to Lord Sri Krsna. This month is full of bhakta vatsalya. Any vrata, even the smallest, will yield huge results. The effect of performing a Kartik Vrata lasts for one hundred lifetimes, whereas ordinary vratas only last for one lifetime! Srimati Radhika is the presiding deity of the holy month of Kartik. Rupa Goswami and others refer to Radharani as Kartik Devi; in other words, Radhika is the goddess or presiding Deity of the Kartik Vrata. - Padma Purana. : quoted by Srila Sanatana Goswami in his Hari-Bhakti Vilasa
Specifically in the month of Damodara, one should daily worship Lord Damodara and take bath early in the morning, give charity and follow a fasting vow. This is the duty of Vaisnavas. - (HARI BHAKTI VILASA 16/3 from SKANDA PURANA)
Oh son Narada, those brahmanas who do not give charity in the month of Karttika, perform sacrifice, chant japa and fast for Lord Hari are the lowest of mankind. - (HARI BHAKTI VILASA 16/25 from SKANDA PURANA)
There is no other month equal to Karttika and there is no other yuga equal to Krta-yuga. There is no other scripture equal to Vedas. There is no other place of pilgrimage equal to Ganges, therefore, the month of Karttika is very dear to the Vaisnavas (people dedicated to Visnu). - (HARI BHAKTI VILASA 16/39,40 from SKANDA PURANA)
Oh great sage, after giving up all varieties of religious functions, one should follow Karttika fast and listen to the narrations of Lord Sri Hari before His Deity form. - (HARI BHAKTI VILASA 16/76 from SKANDA PURANA Lord Brahma speaks to Narada Muni)
One rat (female mouse) had once burnt a ghee lamp which was offered by someone else on Ekadasi day. By doing so, she achieved a rarely achievable human form and at last attained the topmost destination. - (HARI BHAKTI VILASA 16/129 from SKANDA PURANA)
Glories of Kartik
Whatever one does for Krishna–at any time, at any place, under any circumstance–is to one’s eternal benefit:
nehabhikrama-naso ‘sti
pratyavayo na vidyate
“In this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear.”
-Krishna, Bhagavad-gita As It Is, Ch.2
Such is the benefit of devotional service in general. However, during certain times of year–such as appearance anniversaries of Lord Krishna and His devotees–the benefits of one’s service are compounded.
During the month of Damodar, or Kārttika (October/November), rewards for service to Krishna are greater than at any other time of year. For instance, Krishna always likes tulasi leaves, so it’s always a good time to offer tulasi leaves to Krishna. However, in the Hari-bhakti-vilas of Sanatan Goswami, we find these statements:
“The result one obtains by giving ten thousand cows in charity can be obtained by offering only one tulasi leaf to the Supreme Lord during the month of Kārttika.” (7.335)
and…
“Those who worship Lord Hari with an offering of one hundred thousand tulasi leaves during the month of Kārttika certainly advance on the path of pure devotional service, which includes liberation, with each leaf offered. (7.336)”
It is also recommended to offer malati (very fragrant white jasmine-like flowers) to Krishna, and here’s what Hari-bhakti-vilasa says about malati offerings during Kārttika:
“It is better to offer malati flowers to Lord Kesava in the month of Kārttika than to donate gold, cows, or land to worthy recipients.
Malati flowers are pleasing to Lord Kesava (Krishna) in whatever month they are offered. In the month of Kārttika, the offering of malati flowers awards one the merit of performing a horse sacrifice. “
I would have to do some research to find exactly what the merit of performing a horse sacrifice is.
It is easy to understand the importance of the following statement, though, considering that Yamaraja is the universal superintendent in charge of meting out punishment to those who transgress karmic law:
“For a devotee who worships Lord Vishnu with offerings of malati flowers in the month of Kārttika, Yamaraja orders the removal of all his sinful reactions from the account book.” (7.90-92)
Not bad. And the list goes on. Whatever you offer–tulasi, malati, ghee lamps, time, energy, attention–takes on greater significance this month.
Kārttika could be thought of as the ultimate “buy one, get a-whole-lot-more free” sale, or the equivalent of a “super, multi-triple word score” in the game of Scrabble. For a limited time only, whoever is lucky (or greedy, or intelligent) enough to do some service for Krishna during this special month gets a uniquely huge return on their investment. The ultimate return: one becomes more Krishna conscious.

It was during Kārttika that Krishna allowed Himself to be bound with ropes by His mother, Yasoda. Out of loving anger at her transcendentally naughty child, she tied him (dama) around the abdomen (udara) with ropes. Thus the month of Kārttika is also known as the month of Damodara, “He Who was bound around the abdomen”.
Srila Prabhupada discusses this at some length in Nectar of Devotion (quoting Padma Purana):
“During this month, in Vrndavana it is the regulative principle to pray daily to Lord Krishna in His Damodara form. The Damodara form refers to Krishna in His childhood when He was tied up with rope by His mother, Yasoda. Dama means ‘ropes,’ and udara means ‘the abdomen.’ So mother Yasoda, being very disturbed by naughty Krsna, bound Him round the abdomen with a rope, and thus Krishna is named Damodara.” (Chapter 5, page 42)
He elaborates on this in the section “Performing Devotional Service in Kārttika:”
“… in the month of Kārttika (October-November); especially in Vrndavana, there is a specific program for temple worship of the Lord in His Dāmodara form. “Dāmodara” refers to Krishna’s being bound with rope by His mother, Yaśodā. It is said that just as Lord Dāmodara is very dear to His devotees, so the month known as Dāmodara or Kārttika is also very dear to them…
The execution of devotional service during Ūrja-vrata in the month of Kārttika is especially recommended to be performed at Mathurā. This system is still followed by many devotees. They go to Mathurā or Vrndavana and stay there during the month of Kārttika specifically to perform devotional services during this period.”
Prabhupada makes a point to say it is “especially recommended” to perform devotional service during Kārttika in Mathura, or Vrindavana. This is not to say that Kārttika’s benefits are exclusively available there, but devotees who are able to go make the trip if at all possible.
“Urja-vrata” refers to the acceptance of special vows during Kārttika. Devotees often take vows to increase their hearing, chanting, worship, or to observe restrictions in their eating. Making and keeping such vows during the month of Damodara guarantees compounded benefits.
Prabhupada ends Nectar of Devotion’s section on Kārttika with an interesting commentary from Padma Purana:
“…the Lord does not award devotional service to ordinary persons who are not serious about it. But even such unserious persons who execute devotional service according to the regulative principles during the month of Kārttika, and within the jurisdiction of Mathurā in India, are very easily awarded the Lord’s personal service.” (N.O.D., Chapter 12)
If even an “unserious” person can attain Krishna’s personal service, simply by “executing devotional service according to the regulative principles during the month of Kārttika”–wouldn’t it then also be a seriously good time to get serious?
Sri Sri Damodarastakam is sung during Kartika, also known as month of Damodara. As quoted in the Sri Hari Bhakti Vilasa,"In the month of Kartika one should wprship Lord Damodara and daily recite the prayer known as Damodarastaka, which has been spoken by Sage Satyavratra and which attracts Lord Damodara. (Sri Hari Bhakti Vilasa 2.16.198)"
