BG 5.24

One whose happiness is within, who is active and rejoices within, and whose aim is inward is actually the perfect mystic. He is liberated in the Supreme, and ultimately he attains the Supreme.

5.24. The seers, whose dirts have decayed; by whom dualities have been out off; whose self (mind) is controlled; and who are delighted in the welfare of all; they gain the Brahman, the Tranil One.

5.24 He who is happy within his Self and has found Its peace, and in whom the inner light shines, that sage attains Eternal Bliss and becomes the Spirit Itself.

5.24 Yo'ntah etc : Within : For him there is happiness nowhere but within and it does not depend on any external object ; there alone he rejoices; his lustre is there only. But, there is an apparent ignorance [of him] in his worldly dealings. That has been said as - '[A man of realisation] would wander, like a fool, with no inclination for discussion.' (PS, 71)

5.24 He who, renouncing all the experiences of outside objects, 'finds joy within,' i.e., finds his sole joy in experiencing the self; 'who has his pleasure within,' i.e., whose pleasure-garden is the self; and with regard to whom the self increases his happiness by Its own alities like bliss, knowledge, sinlessness, etc.; 'whose light is within,' i.e., who lives, directing his knowledge solely on the self - a person of such a description is the Yogin, who 'having become the Brahman (the self), attains the bliss of the Brahman' i.e., the bliss of experiencing the self.

5.24 Yah antah-sukhah, one who is happy within, in the indwelling Self; and so also antar-aramah, has pleasure within-he disports only in the Self within; similarly, antar-jyotih eva, has his light only within, has the indwelling Self alone as his light; [He has not to depend on the organs like ear etc. for aciring knowledge.] sah yogi, that yogi; yah, who is of this kind; brahma-bhutah, having become Brahman, even while he is still living; adhigacchati, attains; brahma-nirvanam, absorption in Brahman-gets Liberation. Besides,

5.24 He whose joy is within, pleasure is within, and similarly light is within - he is a Yogin, who having become the Brahman, attains the bliss of the Brahman.

5.24 One who is happy within, whose pleasure is within, and who has his light only within, that yogi, having become Brahman, attains absorption in Brahman.
