The mercy of Krishna and rendering of devotional service, all these help one give up the association of non-devotees and material opulence awarded by the external energy, Maya. A pure devotee is never attracted by material opulence, for he understands that wasting time to acquire material opulence is a misuse of the gift of human life.
We should always remember that our body is not for sense gratification, it is for Krishna’s service only. To render very good service to Krishna we should not neglect the upkeep of the body.
When a Krishna Conscious person is elevated to a responsible position, he never becomes puffed up. Just like a tree, when over laden with fruits, becomes humble and lower down, similarly a great soul in Krishna Consciousness becomes humbler than the grass and bows down like the fruitful trees because a Krishna Conscious person acts as the agent of Krishna, therefore he discharges his duty with great responsibility.
In this age, Kali -yuga, to kill the demons means to stop their demoniac activities by the weapon of kirtana, Hari-Sankirtana, which is spread by Lord Chaitanya’s associates.
