The Great Epic of the Bhārata dynasty 13.14.41

Some of those ascetics subsisted upon air and some upon water, some were devoted to Japa or the silent recitation of sacred Mantras, and some were engaged in cleansing their souls by practising the virtues of compassion while some amongst them were Yogins devoted to the abstraction of Yoga-meditation. Some amongst them subsisted upon smoke only, and some subsisted upon fire, and some upon milk. Thus was that retreat adorned with many foremost of regenerate persons. And some there were amongst them that had taken the vow of eating and drinking like kine,--that is, by giving up the use of the hands at once. And some used only two pieces of stone for husking their grain, and some used their teeth only for that purpose. And some subsisted by drinking only the rays of the moon, and some by drinking only froth. And some had betaken themselves to vow of living like deer. And some there were that lived upon the fruits of the Ficus religiosa, and some that used to live upon water. And some dressed themselves in rags and some in animal skins and some in barks of trees. Indeed, I beheld diverse ascetics of the foremost order observing these and other painful vows. I desired then to enter that asylum. Verily, that asylum was honoured and adored by the deities and all high-souled beings, by Siva and others, O Bharata, and by all creatures of righteous acts. Thus addressed, it stood in all its beauty on the breast of Himavat, like the lunar disc in the firmament.
