prajahāti yadā kāmān sarvān pārtha manogatān
ātmany-evātmanā tuṣṭa: sthita-prajñas-tadocyate – 2.55
Lord Krishna said: When one relinquishes all desires engendered by the mind, and remains contented in his own within, he is said to be a Sthita-prajña, one with steady consciousness.
For the mind to get absorbed within, the seeker has to leave all desires, secular and spiritual alike. Desires have no ground in a truly seeking mind, as the Self is unchanging, always blissful. Besides the Self, the seeker needs nothing to make him full. As he is already the Self, where is the question of desiring it at all?
He thus thinks: “Desires grip me, because I fail to introspect properly. Even when I desire an object, it will not enter me to give delight. My Self is delight personified. Why then make the error of desiring anything else? In sleep, am I not contented fully? Here now remaining wakeful, I shall plunge into myself.”
Such introspection leads to dropping of all desires, making one immersed wakefully into the Self.
