Here some information I thought that may be useful.
I am pasting it here ( against my practice)
1. Then, it is said, Samkriti approached the venerable Avadhuta, Dattatreya, and questioned: Venerable Sir, Who is an Avadhuta ? What is his condition ? What his characteristic ? And what his worldly existence ? To him replied the venerable Dattatreya, the most compassionate:
2. The Avadhuta is so called because he is immortal [akshara]; he is the greatest [varenya]; he has discarded worldly ties [dhutasamsarabandhana]; and he is the indicated meaning of the sentence 'Thou art That', etc., [tattvamasyadi-lakshya].
3. He who rests constantly in himself, after crossing (the barrier of) castes and stages (of social position) and thus rises above varnas and asramas and is in union (with God) is said to be an Avadhuta.
4. His joy [priya] is (to be envisaged as) the head; delight [moda] is his right wing; great delight [pramoda] his left wing; and bliss (his very self). Thus he assumes a fourfold condition.
5. One should identify Brahman neither with the head nor with the middle part nor with the bottom but with (what remains in the shape of) the tail, since it is said that Brahman is ‘the Tail’ and substratum. Thus, those who contemplate this fourfold division attain the supreme Goal.
6. Not by rituals, not by begetting children, not by wealth, but by renunciation [tyaga] alone a few attained immortality.
7. His (the Avadhuta’s) worldly existence consists in moving about freely, with or without clothes. For them there is nothing righteous or unrighteous; nothing holy or unholy. Through all-consuming, correct knowledge [samgrahaneshti] (the Avadhuta) performs Ashvamedha sacrifice within (himself). That is the greatest sacrifice and the great Yoga.
