Day after day let the seeker practise harmony of soul: in a secret place, in deep solitude, master of his mind, hoping for nothing, desiring nothing.

Let him find a place that is pure and a seat that is restful, neither too high nor too low,with sacred grass and a skin and a cloth thereon.

On that seat let him rest and practise meditation for the purification of the soul: with the life of his body and soul in peace; his soul in silence before the One.

With upright body, head and neck, which rest still and move not; with inner gaze which is not restless, but rests still within the eyebrows; with soul in peace, and all fear gone, and strong in the vow of holiness, let him rest with mind in harmony, his soul on me, his God supreme.

Bhagavad Gita (India ca 500 BC)
