नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना | न चाभावयतः शान्तिरशान्तस्य कुतः सुखम् ||२-६६||

Chapter 2 · Verse 66
Sankhya Yoga
सांख्ययोग
In plain words
You must integrate your mind through meditation to find true happiness. Without self-discipline, you cannot cultivate jnana, which is spiritual knowledge, or focus your thoughts. Lacking this focus, your mind remains restless, chased by desires that block your inner peace. True joy only begins when this mental thirst quietens and you rest in your true self.
Translation
2.66 There is no Buddhi for the unintegrated, nor for him is there contemplation of the self, and for him without contemplation of the self, there is no peace; and for one lacking peace, where is happiness?
Meaning
The man who cannot fix his mind in meditation cannot have knowledge of the Self. The unsteady man cannot practise meditation. He cannot have even intense devotion to Selfknowledge nor can he have burning longing for liberation or Moksha. He who does not practise meditation cannot possess peace of mind. How can the man who has no peace of mind enjoy happinessDesire or Trishna (thirsting for senseobjects) is the enemy of peace. There cannot be an iota or tinge of happiness for a man who is thirsting for sensual objects. The mind will be ever restless and will be hankering for the objects. Only when this thirsting dies does man enjoy peace. Only then can he meditate and rest in the Self.
Word by word
न not अस्ति is बुद्धिः knowledge (of the Self) अयुक्तस्य of the unsteady न not च and अयुक्तस्य of the unsteady भावना meditation न not च and अभावयतः of the unmeditated शान्तिः peace अशान्तस्य of the peaceless कुतः whence सुखम् happiness.
