CHĀNDOGYA UPANISHAD · 3.11.6

नान्यस्मै कस्मैचन ।
यद्य् अप्य् अस्मा इमाम् अद्भिः परिगृहीतां धनस्य पूर्णां दद्याद् एतद् एव ततो भूय इति ॥

nānyasmai kasmaicana ।
yady apy asmā imām adbhiḥ parigṛhītāṃ dhanasya pūrṇāṃ dadyād etad eva tato bhūya iti ॥

But no one should tell it to anybody else, even if he gave him the whole sea-girt earth, full of treasure, for this doctrine is worth more than that, yea, it is worth more.
