The devotee will not only sing spiritual songs and chants (bhajan and kiirtan). They are not seasoned devotees! Those spiritual aspirants who move speedily on the path of evolution towards the Supreme Consciousness will never be blind to the sufferings of countless people around them due to the lack of a solid social system, solid economic system and human feeling. If anyone is blind to the ill-management of the social system, they have not been able to understand the Supreme Consciousness fully. If they do so, they will have a subjective approach but not objective adjustment. But when devotees will move towards the Supreme, their approach will be "salvation for self and service to humanity." They go on moving toward the Supreme Consciousness while serving humanity. When humanity is neglected, "salvation for self" is also destroyed. Hence the devotee must be ready to serve humanity. The spiritual aspirants who do not render social service do not have real devotion. In their devotion lies selfishness. The devotees who are selfish do not attain God. Those who are devotees are workers. They will never be afraid of work. They will do maximum work.
