The Gorakhbodh

Gorakh -- O Lord (Svami), you are the Master Teacher (Satguru Gosain), and I am but a disciple: may I put a question, which you would kindly reply to and resent not? To start with, what ideal (lacch) should the disciple put before him? Do tell me for you are the true Teacher.
Macchendra: Let the unattached (awadhu, avadhuta) live at the monastery (hat) or be on the road, resting in the shadow of the trees; he should renounce desire, cruelty, greed, delusion, and the illusion of Samsar (Kama, Krodha, Lobha, Moha and Samsar ki Maya); he should hold converse (gosht) with himself and contemplate the Endless (Ananta); he should sleep little and eat little. In the beginning the disciple should live thus. Thus speaks Macchendra. [2]
Gorakh: What should he see, what contemplate, and what treat as the essence (sar); with what should he shave his head and with the knowledge of what should he try to cross (the ocean of Samsar)?
Macchendra: He should see himself, contemplate the Endless (Ananta), and fix upon Reality as the essence; he should shave his head with (or after receiving) the word of the teacher (Guru ka Shabda), and should cross over with the aid of Divine knowledge (Brahma Gyana). [4]
Gorakh: What is the teaching (upadesh) of the Guru's order or doctrine (Ades)? Where does the void (Sunya) reside? Who is the Guru of the word (Shabda)?
Macchendra: The most wonderful (anupam) is the teaching of the Guru (Ades); the void (Sunya) resides within us and Realisation (parcha or parichaya) is the Guru of the word (shabda). [6]
