Chandogya Upanishad 2.17.2

2.17.2

sa ya evam etāḥ śakvaryo lokeṣu protā veda \
lokī bhavati sarvam āyur eti \
jyog jīvati \
mahān prajayā paśubhir bhavati \
mahān kīrtyā \
lokān na nindet \
tad vratam \\217.2\

2. He who knows thus these verses of the Śakvarī Sāman as woven upon the worlds becomes possessor of a world, reaches a full length of life, lives long, becomes great in offspring and in cattle, great in fame. One should not find fault with the worlds. That is his rule.
