This process of Krsna consciousness is so nice that svalpam apy asya dharmasya, even slightly executed in due time…
Because the process is we are educating people to chant Hare Krsna to practice, so in due time, Hare Krsna at the time of death especially, if we can chant this holy name of God, Hare Krsna, then our life is successful. So unless we practice, how it will be possible to chant at the time of death? Because at the time of death the whole system, anatomical-physiological system, becomes disturbed, in bewilderedness, in coma, in unconsciousness. But still, if one has practiced, there is possibility of chanting the holy name of the Lord, Hare Krsna, Narayana. Then that is success of life. In Bengali there is a proverb, bhajana kara sadhana kara murti janle haya[?], that "Whatever you are executing as a bhajana, sadhana, that's all right, but it will be tested at the time of your death." It will be test. Just like a parrot is chanting "Hare Krsna, Hare Krsna," but when some cat comes in, "Kaw-kaw-kaw." No. Then missing. So parrot life will not help you. You must be really chanting, without any offense. Then it is possibility that at the time of death…
Death will be there. You may be very proud of your body, that "I am permanent." No. "As sure as death." And after death you have to change your body. Tatha dehantara-praptih [Bg. 2.13]. That we do not know, what kind of body I will enjoy. "Now I have got sethji's body," that's all right. But your karma will decide the next body.
