Chapter 5 Sanyasa Yoga Verse 22
Shloka
Yo’ntah sukho’ntaraaraamas tathaantarjyotir eva yah;
Sa yogee brahma nirvaanam brahmabhooto’dhigacchati.
Translation
He who is ever happy within, who rejoices within, who is illumined within,
such a Yogi attains absolute freedom or Moksha, himself becoming Brahman.
Interpretation
In this sloka Lord Krishna continues his lecture on the qualities of a Yogi and why he is always a happy man. Lord Krishna says that a yogi is the one who is always happy within himself. He will never look outside for happiness. He will always rejoice within which means when he feels happy he will just celebrate that with himself. Lord Krishna says that Yogi is also a person who is illuminated within, which means that the person has lot of wisdom inside him. Such kind of person is a yogi who attains absolute freedom and attains moksha and himself becomes a Brahman.
Extending Interpretation to Mankind’s Life!
This sloka talks about how a person becomes a Brahman himself. Attaining moksha is one side and himself becoming Brahman is another side of the spiritual evolution. Let us take the example of Gautama Buddha. We know Gautama was a prince who led a happy and luxurious life in the palace enjoying all the comforts. Seeing people suffer with disease and seeing them die, he decides to leave everything and find out the secret of Life and Death. He left his wife, son and the entire kingdom and goes searching for the truth.
That began the journey of spirituality. Buddha attained enlightenment under the Bodhi tree in Gaya and he became Buddha. After getting the enlightenment he started feeling happy within, he rejoices within and he got illuminated within. We can see the illumination of Buddha in his teachings. Thus Buddha became a yogi and with all the knowledge he himself became Brahman. Today Buddhism is a religion in many pars of East Asia and Buddha is worshipped as God. What else you need a proof that a man with his actions and renunciation can become Brahman one day.
