"Even a child comes and offers his respect, it is taken into account, that 'Here is a devotee.' He does not know anything. Simply by seeing the chanting and dancing—you'll see practically—even a small child, he dances, he claps, he enjoys. He takes part. So the temple means to give chance to everyone, even to the child, to advance one step to Kṛṣṇa consciousness. One step. Svalpam apy asya dharmasya trāyate mahato bhayāt (BG 2.40). Even little is accepted and is done, it becomes into account. Just like if you deposit even two annas in the bank, it is kept on your account. It will increase with interest. Similarly, devotional service even done very little, it is not lost. It is not lost. In the śāstra it is said that even it is lost... not lost. Suppose some reason a man comes and joins this Kṛṣṇa consciousness movement, and in the middle he falls down; he does not make further progress because he falls down. But whatever he has done, that is permanent credit. That will never be lost. Even he stops, then from that point, again he will begin as soon as there will be chance. But whatever he has done, that is a permanent credit. That is the instruction of śāstra."
