Pradyumna: "When Lord Ṛṣabhadeva saw that the general populace was very antagonistic to His execution of mystic yoga, He accepted the behavior of a python in order to counteract their opposition. Thus He stayed in one place and lay down. While lying down, He ate and drank, and He passed stool and urine and rolled in it. Indeed, He smeared His whole body with His own stool and urine so that opposing elements might not come and disturb Him."
Prabhupāda: Yarhi vāva sa bhagavān lokam imaṁ yogasyāddhā. (SB 5.5.32) So this is another process of yoga-siddhi, ājagara-vṛtti, ājagara, python, lying down in one place, eating and passing urine, stool, everything. Ājagara-vṛtti. Ājagara, the python, it lies down in one place, big, big python, sometimes covered by the earth, but still, he gets his food. Big, big animals enter into the home of the python. And the python can eat even a full horse, what to speak of other animals. But still, Kṛṣṇa supplies him food. He hasn't got to go anywhere. So sometimes saintly persons, they sit down in one place. If Kṛṣṇa sends him food he will eat; otherwise he will starve. In our ācārya-sampradāya, Mādhavendra Purī, Bilvamaṅgala Ṭhākura, they were doing that. In Vṛndāvana Bilvamaṅgala Ṭhākura, he was blind. He was sitting in one place, and Kṛṣṇa used to come and supply him milk.
