the devotees are totally surrendered to Krishna, and they are solely engaged in the service of Krishna. They are not afraid of any condition of life, this is because they are always doing devotional service to Krishna, the Supreme Personality of Godhead.
It is the devotion alone which pleases Krishna, not any material qualification or qualities. When Krishna is pleased, all the material qualifications required for serving, automatically manifests in devotee.
The Supreme Lord has unlimited qualities and pastimes. So it is practically not possible to understand Him through our material senses. Then why are we trying to define Him in so many ways through so many comparisons (as it is done in this verse) ?
no conditioned soul should be depressed by thinking that he will never be out of the clutches of matter, for there is every possibility of being rescued, exactly as it is possible for a log, which is floating down a river to come to rest on the bank, and thus being saved from being forced to drift further downstream.
Prahlad Maharaj in Srimad Bhagavatam gives us the formula to please Krsna - bhaktya tutosh bhagavan gaja yuth paya - 'O Lord you are pleased by devotion and the example is King of Elephants (Gajendra) - (Bhag 7.9.9)
since the sankirtana movement was first set in motion five hundred years ago by Sri Caitanya Mahaprabhu's desire that it spread all over the universe, the Krsna consciousness movement, in continuity of that same motion, is now spreading all over the world, and in this way it will gradually spread all over the universe.
