Chapter 2Verse 66
Sankhya Yoga
नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना। न चाभावयतः शान्तिरशान्तस्य कुतः सुखम्॥
nāsti buddhir ayuktasya na cāyuktasya bhāvanā, na cābhāvayataḥ śāntir aśāntasya kutaḥ sukham
Translation
The undisciplined mind has no clear understanding and no steady reflection. Without reflection there is no peace, and without peace, where is happiness?
A scattered mind finds no peace. And without peace, where would happiness even come from?
What does this mean?
This traces a chain most people feel but never name. A mind pulled in ten directions can't think clearly, and without clear thinking there's no steadiness. Without steadiness there's no peace, and a restless mind never quite reaches happiness no matter how hard it chases it.
In simple words
Krishna traces a chain most people feel but never spell out. A scattered mind can't think clearly. Without clear thinking there's no steady reflection. Without that there's no peace. And without peace, where would happiness even come from?
The deeper idea
The verse is a short causal sequence running from an undisciplined mind to the absence of happiness, with each step making the next one follow. The starting point matters: it isn't bad luck or hard circumstances that block happiness here, it's a mind that was never steadied, so it can't hold a clear thought long enough for peace to form. The implication is that chasing happiness directly, while skipping the work on the mind, is chasing the last link in a chain whose first links aren't in place.
How it applies to life
Notice how a genuinely frazzled day resists every attempt to enjoy anything. You sit down to relax and the mind is still sprinting, so the rest doesn't land. This verse says that's the normal order of things: the scattered mind has to settle before clear thinking is possible, and peace and satisfaction come after that, not before. It reframes 'I just need to unwind' as 'I need to actually steady my attention first'.
