Devikalottara

 The means by which this mind, which is restless and moves about quicker than the wind, can be brought under control, is indeed the means to obtain liberation; it indeed is what is good for those who seek the permanent Reality;

it itself is Pure Consciousness and the state of firmness; moreover, it alone is the righteous duty to be followed by discerning aspirants; it alone is the pilgrimage to holy waters; it alone is charity; it alone is austerities. Know that there is no doubt about this. When the mind moves even a little, that is samsara; when the mind abides firmly and motionlessly, that is mukti. This is certain. Therefore know that the wise man must hold his mind firm by supreme Self-awareness. The happiness attained in this solitude is the highest, boundless bliss. Which learned persons will not revel in that Supreme Reality, in which there is absolutely no action? Tell me.
