The Siddha Siddhanta Paddhati is a very early extant Hatha Yoga Sanskrit text attributed to Gorakshanath by the indigenous tradition, as Feuerstein (1991: p. 105) relates:
"One of the earliest hatha yoga scriptures, the Siddha Siddhanta Paddhati, contains many verses that describe the avadhuta. One stanza (VI.20) in particular refers to his chameleon-like capacity to animate any character or role. At times, it is said, he behaves like a worldling or even a king, at other times like an ascetic or naked renunciant."
