THEN THAT BECOMES THEIR SERVICE

Discussion of topics in the Bhagavatam and Gita is not going to be appealing to everyone. And the movement is divinely designed so that it is not even necessary for everyone to engage in philosophical discussions in Krishna consciousness. The all-merciful Lord has made Krishna consciousness as simple as possible for us in the age of distraction.
But there will be some of us who actually relish discussing Krishna consciousness in a philosophical way even with our limitations as creatures born into the Kali yuga. Who find the taste of every word of Srila Prabhupada filled with devotional nectar and so intoxicating that they really have no desire to do anything else than to constantly relish hearing the message of Godhead emanating from the lips of the Pure Devotee. Chanting and discussing.
That then becomes their service. To simply hear and chant.
