4.29.76

bhaktiḥ kṛṣṇe dayā jīveṣv akuṇṭha-jñānam ātmani /
yadi syād ātmano bhūyād apavargas tu saṃsṛteḥ //
yathā tṛṇa-jalūkeyaṃ nāpayāty apayāti ca /
na tyajen mriyamāṇo 'pi prāg-dehābhimatiṃ janaḥ //

76. Just as the leech passes on and does not pass on (because it does not abandon the hold of the first piece of straw till it takes hold of a second), so also the Jīva does not lose his attachment to his body even at the time of departing from it.
