A Brahmana who retains in his memory the Rig-veda is not stained by guilt, though he may have destroyed these three worlds, though he may eat the food of anybody.
ऋक्संहितां त्रिरभ्यस्य यजुषां वा समाहितः । साम्नां वा सरहस्यानां सर्वपापैः प्रमुच्यते ॥ २६२ ॥
He who, with a concentrated mind, thrice recites the Riksamhita, or (that of the) Yagur-veda; or (that of the) Sama-veda together with the secret (texts, the Upanishads), is completely freed from all sins.
ऋचो यजूंषि चान्यानि सामानि विविधानि च । एष ज्ञेयस्त्रिवृद्वेदो यो वेदैनं स वेदवित् ॥ २६४ ॥
The Rikas, the Yagus (-formulas) which differ (from the former), the manifold Saman (-songs), must be known (to form) the triple Veda; he who knows them, (is called) learned in the Veda.
आद्यं यत् त्र्यक्षरं ब्रह्म त्रयी यस्मिन् प्रतिष्ठिता । स गुह्योऽन्यस्त्रिवृद्वेदो यस्तं वेद स वेदवित् ॥ २६५ ॥
The initial triliteral Brahman on which the threefold (sacred science) is based, is another triple Veda which must be kept secret; he who knows that, (is called) learned in the Veda.
