yāvān artha uda-pāne
tāvān sarveṣu vedeṣu
aho bata śva-paco ’to garīyān
yaj-jihvāgre vartate nāma tubhyam
tepus tapas te juhuvuḥ sasnur āryā
brahmānūcur nāma gṛṇanti ye te
yāvān — all that; arthaḥ — is meant; uda-pāne — in a well of water; sarvataḥ — in all respects; sampluta-udake — in a great reservoir of water; tāvān — similarly; sarveṣu — in all; vedeṣu — Vedic literatures; brāhmaṇasya — of the man who knows the Supreme Brahman; vijānataḥ — who is in complete knowledge.
All purposes served by a small well can at once be served by a great reservoir of water. Similarly, all the purposes of the Vedas can be served to one who knows the purpose behind them.
