(Kadamba Kanana Swami, 11 October 2011, Melbourne, Australia, Home Program)
In the Bhagavad-gita 10.35, Krsna says that of all the months, “I am marga-sirsa,” which is a name for the November-December period. It is said that before Krsna, first comes Radha – Radha-Krsna, Radha-Syam, Sita-Ram, like that. First the consort of the Lord is mentioned. Therefore the month of Kartik, which comes before this month of marga-sirsa, is a month of Radharani. It is a month when we are meditating on pure devotional service because she is the proprietor of pure devotional service! No compromise at all, no self-interest whatsoever, only the interest of Krsna in mind and nothing but the interest of Krsna.
That is pure devotional service and that is found in Srimati Radharani, so this month of Kartik is about that. So everyone who is ordinarily sort of compromised in his devotional service, in the month of Kartik, will try for pure devotional service. In this month, one can take vows to perform some special service because this month is the month of Srimati Radharani. She is especially noticing the service that we render and when she recommends us to Krsna, then Krsna will also be inclined towards us. Radharani is very compassionate and soft-hearted. Therefore, this month is especially a very favorable time to try and attract the mercy. In that way, we prepare for the month of Kartik and see what special service can we offer?
