"The caterpillar transports itself from one leaf to another by capturing one leaf before giving up the other. Similarly, according to his previous work, the living entity must capture another body before giving up the one he has. This is because the mind is the reservoir of all kinds of desires."
Śrīmad-Bhāgavatam 4.29.76-77
