Within the material world, one’s material body is always subject to birth and decay. Similarly, the life air [prāṇa] is harassed by hunger and thirst, the mind is always anxious, the intelligence hankers for that which cannot be obtained, and all of the senses are ultimately exhausted by constant struggle in the material nature. A person who is not bewildered by the inevitable miseries of material existence, and who remains aloof from them simply by remembering the lotus feet of the Supreme Personality of Godhead, is to be considered bhāgavata-pradhāna, the foremost devotee of the Lord.
