The Great Epic of the Bhārata dynasty 12.232.32

12.232.32

api varṇāvakṛṣṭastu nārī vā dharmakāṅkṣiṇī |
tāvapyetena mārgeṇa gacchetāṃ paramāṃ gatim || 32 ||

With the senses and the mind withdrawn from everything else, the Yogin (for practice) should betake himself to empty caves of mountains, to temples consecrated to the deities, and to empty houses or apartments, for living there. One should not associate with another in either speech, act, or thought. Disregarding all things, and eating very abstemiously, the Yogin should look with an equal eye upon objects acquired or lost. He should behave after the same manner towards one that praises and one that censures him. He should not seek the good or the evil of one or the other. He should not rejoice at an acquisition or suffer anxiety when he meets with failure or loss. Of uniform behaviour towards all beings, he should imitate the wind. Unto one whose mind is thus turned to itself, who leads a life of purity, and who casts an equal eye upon all things,--indeed, unto one who is ever engaged in Yoga thus for even six months,--Brahma as represented by sound appears very vividly. Beholding all men afflicted with anxiety (on account of earning wealth and comfort), the Yogin should view a clod of earth, a piece of stone, and a lump of gold with an equal eye. Indeed, he should withdraw himself from this path (of earning wealth), cherishing an aversion for it, and never suffer himself to be stupefied. Even if a person happens to belong to the inferior order, even if one happens to be a woman, both of them, by following in the track indicated above, will surely attain to the highest end.
