Adi Shankara

“ In the silence is the highest peace, because wavering is the intellect's unreal work; there the knowers of the Eternal, mighty-souled, enjoy unbroken happiness of partless bliss, recognizing the Self as the Eternal.
There is no higher cause of joy than silence where no mind-pictures dwell; it belongs to him who has understood the Self's own being; who is full of the essence of the bliss of the Self. ”

“ His food is what is freely offered, eaten without anxiety or sense of poverty; his drink is the pure water of the streams; he moves where fancy leads him, unconstrained; he sleeps by the river-bank, or in the wood; for his vesture is- one that grows not old or worn; his home is space; his couch, the world; he moves in paths where the beaten road is ended; the wise man, delighting in the supreme Eternal. ”

“ Whether walking or standing, sitting or lying down, or wherever he may be, let the sage dwell according to his will, the wise man finding joy ever within himself.
No distinctions of place or time, position or space are to be regarded as bringing release from bondage, for the mighty-souled, who has perfectly attained to reality. Of what avail are the rites of religion for one who has attained to wisdom? ”
