The best means of spiritual realization is chanting the holy name of the Lord.
Bhagavad Gita 6.11-12,
Krishna Consciousness is not a matter of faith but it is the science of self realization.
For the one who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his very mind will be his greatest enemy.
Death is not a big thing, what is important is God's service.
