The three-eyed Lord we worship, sweet augmenter of prosperity. As a (ripe) cucumber from its stem, so may we be freed from the bonds of death; (may we) never be reft from immortality. (Rig Veda, 7.59.12)
Having well ascertained the Self, the goal of the Vedantic knowledge, and having purified their minds through the yoga of sannyasa, the seers, never relaxing their efforts, en joy (here) supreme Immortality and at the time of the great end attain complete freedom in Brahman. (Mundaka Upanishad, 3.2.6)
As pure water poured into pure water becomes one with it, so, O Gautama, does the Self of the contemplative sage who knows (Brahman). (Katha Upanishad, 2.1.15)
Few only know the truth.
The rest will hate and laugh at thee, great one;
But pay no heed.
O thou, the free, from place to place, and help Them out of darkness, Maya’s veil.
Without the fear of pain or search for pleasure, go be yond them both,
Sannyasin bold Say
Om Tat Sat, Om! (The Song of the Sannyasin)
It may be that I shall find it good to get out side of my body to cast it off like a disused garment. But I shall not cease to work! I shall in spire men everywhere, until the world shall know that it is one with God. (The Complete Works of Swami Vivekananda, 5.414)
