Verse
यथा सर्वगतं सौक्ष्म्याद् आकाशं नोपलिप्यते ।सर्वत्रावस्थितो देहे तथात्मा नोपलिप्यते ॥
yathā sarvagataṃ saukṣmyād ākāśaṃ nopalipyatesarvatrāvasthito dehe tathātmā nopalipyate
As the all-pervading ether is not affected by reason of its subtlety, so seated everywhere in the body, the Self is not affected.
Gītā 13·33
