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)

.

I advise you to take a liking to real, physical solitude.
I don't mean that you need to go into the desert as the old hermits did. It will be enough to stay in your room or walk in the garden or remain in any other place where you find it easy to recollect yourself.

There you should withdraw your mind within your own heart and refresh yourself with some solid reflection, some holy thoughts and some useful reading.

St. Francis of Sales (France 1567-1622)
