By abandoning the fruits of action a man of restrained mind attains to abiding peace. But the one with unrestrained mind, being prompted by desire for the fruits of action, gets bound.
Be ‘unattached’; let things work; let brain centres work; work incessantly, but let not a ripple conquer the mind. Work as if you were a stranger in this land, a sojourner; work incessantly, but do not bind yourselves…
— Swami Vivekananda (CW, 1:56)
An aspirant who is unattached to the contactual experiences of the external world, gains the joy that is in the Self within. He enjoys unending bliss with his mind absorbed in communion with Brahman.
What we call happiness and good here are but particles of that eternal Bliss [of the Self]. And this eternal Bliss is our goal.
— Swami Vivekananda (CW, 3:128)
Whatever enjoyments are there born of sense contact, they are sources of suffering only. For, they are with a beginning and an end. A wise man finds no delight in them.
Do not go for glass beads leaving the mine of diamonds! This life is a great chance. What, seekest thou the pleasures of the world?—He [God] is the fountain of all bliss. Seek for the highest, aim at that highest, and you shall reach the highest.
— Swami Vivekananda (CW, 6:262)
The Yogin whose happiness is within, whose resting place is within, who likewise experiences the light within—he realises himself to be the Spirit and attains to beatitude in Brahman.
As soon as you think you are bound, no more you are Brahman, the Self, who wants nothing, whose light is inside. All His pleasures and bliss are inside; perfectly satisfied with Himself, He wants nothing, expects nothing, perfectly fearless, perfectly free. That is Brahman. In That we are all one.
— Swami Vivekananda (CW, 3:348)
