Just as a person traveling on the road rests one foot on the ground and then lifts the other, or as a worm on a vegetable transfers itself to one leaf and then gives up the previous one, the conditioned soul takes shelter of another body and then gives up the one he had before.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
व्रजंस्तिष्ठन् पदैकेन यथैवैकेन गच्छति । यथा तृणजलूकैवं देही कर्मगतिं गतः
vrajaṃstiṣṭhan padaikena yathaivaikena gacchati | yathā tṛṇajalūkaivaṃ dehī karmagatiṃ gataḥ
