बाह्यस्पर्शेष्वसक्तात्मा विन्दत्यात्मनि यत्सुखम् । स ब्रह्मयोगयुक्तात्मा सुखमक्षयमश्नुते ॥
bāhyasparśeṣvasaktātmā vindatyātmani yatsukham | sa brahmayogayuktātmā sukhamakṣayamaśnute ||
Translation
One whose self is unattached to external contacts finds the happiness that is in the Self. United with Brahman through yoga, such a person enjoys imperishable bliss.
Interpretation
There are two kinds of happiness: external (derived from objects, relationships, and experiences) and internal (derived from the Self itself). External happiness is real but temporary — the contact ends and the happiness evaporates. The happiness of the Self (atmananda) requires nothing external to trigger it; it is the natural state of pure consciousness. The yogi who has turned inward and discovered this inexhaustible inner spring enjoys akshaya (imperishable) bliss — not because they have more, but because they need nothing more.
