KAṬHA UPANISHAD · 1.2.22

अशरीरँ शरीरेष्वनवस्थेष्ववस्थितम् ।
महान्तं विभुमात्मानं मत्वा धीरो न शोचति ॥ २२॥

aśarīram̐ śarīreṣvanavastheṣvavasthitam ।
mahāntaṃ vibhumātmānaṃ matvā dhīro na śocati ॥ 22॥

Realising the Bodiless in bodies, the Established in things unsettled, the Great and Omnipresent Self, the wise and steadfast soul grieves no longer.
