When one finds God within oneself, this is true intelligence, true wisdom.

Sankhya Yoga

Chapter 2, Verse 55

 

śrī bhagavān uvāca 

prajahāti yadā kāmān 

sarvān pārtha manogatān 

ātmany-evātmanā tuṣṭaḥ 

sthita-prajñās tad-ocyate

 

The Lord says: When a man expels, O Paartha, all desires from the mind, and is satisfied in the Self by the Self, then is he considered stable in intelligence. 

After the total cessation of all desires in the mind, then the sadhak, the bhakta, perceives the true nature of the Eternal, the true nature of God within the Self: within himself, the Supreme Self awakens. The supreme intelligence awakens. The intelligence which Krishna talks about before is the intelligence which the mind understands. Here Krishna is saying that in the one who is satisfied in the Self Itself, what arises is wisdom, Brahma Jyaan, the knowledge of the Divine, through the continued and devoted practice of attaining the Divine. When the mind is unshakably fixed on God, then one becomes stable, of stable mind. When one finds God within oneself, this is true intelligence, true wisdom.
