KAṬHA UPANISHAD · 2.2.13

नित्योऽनित्यानां चेतनश्चेतनानाम्
एको बहूनां यो विदधाति कामान् ।
तमात्मस्थं येऽनुपश्यन्ति धीराः
तेषां शान्तिः शाश्वती नेतरेषाम् ॥ १३॥

nityo’nityānāṃ cetanaścetanānām
eko bahūnāṃ yo vidadhāti kāmān ।
tamātmasthaṃ ye’nupaśyanti dhīrāḥ
teṣāṃ śāntiḥ śāśvatī netareṣām ॥ 13॥

The One Eternal in many transient, the One Conscious in many conscious beings, who being One ordereth the desires of many; the calm and strong who behold Him in the self as in a mirror, theirs is eternal peace and ’tis not for others.

Sri Aurobindo · CWSA 18, p. 122
