Sree Sree Guru Gaurangau Jayatah!
In Padma purana it is instructed what is to be done and what is not to be done. What we have to do? That which reminds us of Sri Krishna. Always we must remember Sri Krishna, Vishnu. Whatever action reminds us of Sri Krishna that is allowed. And what not to do? By which we forget Sri Krishna. We should never forget Sri Krishna. If any action makes us forget Sri Krishna that is a crime. That we should not do. There are list of commandments and prohibitions—64 kinds of principle devotion you will find in Bhakti-rasamirta-sindhu; in Srimad Bhagavatam nine forms of devotion are described and Chaitanya Mahaprabhu has further said five forms of principle devotion—Sadhu Sanga, Nama Kirtan, Bhagavat Shravan, Mathuravas, Sraddhaya Sri Murti Seva. Association of bona fide sadhus, sadhu sanga, is the first one. Nama Kirtan—chanting of the Holy name of Sri Krishna. Bhagavat Shravan—listening to Srimat Bhagavatam from a Bhagavat, from a sudha bhakta. Sudha bhakta is also designated as Bhagavat. You will have to hear Bhagavatam from a Bhavagat, Vaishnav. Mathuravas—where shall we stay? Holy place of pastimes of Sri Krishna. We have to stay in the transcendental realm. Wherever devotees sing the glories of Supreme Lord that is also considered as transcendental realm, you are to stay there. And with faith, firm faith you worship Sri Krishna. Among these 5 principle forms of devotion He has given foremost emphasis to Nam Sankirtan. Nam Sankirtan is the best. If anybody can perform Nam Sankirtan, chanting of the Holy Names without offences, it is the best. It removes all afflictions. The root cause of our afflictions is forgetfulness of our relationship with Sri Krishna. So you are to undo this. We have forgotten Sri Krishna. For that reason Sri Krishna’s maya, illusory energy has entrapped us and we have been curtailed in the three primal qualities of the external potencies. We have been hurled down in this world in birth, death and three-fold afflictions.
