Real Duty
The living force is always dynamic; therefore he cannot stop discharging duties. Real duty begins in Krishna Consciousness.

Cause of Suffering
A bonafide devotee of Lord Krishna is always pained to see the fallen condition of the whole world. Srila Bhakti Siddhanta Sarasvati Thakura used to say, “There is no scarcity of anything within this world, the only scarcity is of Krishna Consciousness.” That is the vision of all the pure devotees. Because of this lack of Krishna Consciousness in human society, people are suffering terribly, being maerged in an ocean of nescience and sense gratification. A devotee onlooker is very much aggrieved to see such a situation in the world. — Sri Chaitanya Caritamrita, Adi Lila, Chapter 13, Text 67.
