Sree Sree Guru Gaurangau Jayatah!
nayam atma pravacanena labhyo
na medhaya na bahuna srutena
yam evaiva vrnute tena labhyas
tasyaiva atma vivrnute tanum svam
"God cannot be attained, realized by delivering lectures, by intellect, by becoming a great erudite scholar. The Supreme Lord will reveal His own Eternal Form only to a bona fide surrendered soul."
As my Divine Master has ordered me, I should speak whatever I have heard from Him and from my superiors, guruvarga (the line of teachers in the preceptorial channel). That recitation will purify my mind and take me to the Transcendental Realm. I should not speak to please the worldly people. If I do so, my spiritual life will be spoiled.
If I go on speaking about worldly things, my mind will become attached to worldly things. If I speak about Krishna, my mind will go there. This is called "chanting"—chanting of the glories of the Supreme Lord, His Name, Forms, Attributes, and Pastimes. Chanting is one form of devotion; hearing is also a form of devotion. Pariksit Maharaja, by hearing only, got the ultimate goal of life. If we speak about worldly things, then worldly, temporary things will come to our minds. Ultimately, we shall have frustration in our life.
