Avadhuta Gita
धूलिधूसरगात्राणि धूतचित्तो निरामयः। धारणाध्याननिर्मुक्तो धूकारस्तस्य लक्षणम् ॥८॥
The syllable DHU of Avadhuta indicates that, though his body is besmeared with grey dust from lack of body-consciousness, his mind is pure and healthy. He no longer needs to practise concentration and meditation.
