Chandogya Upanishad 7.1

Nârada approached Sanatkumâra and said, 'Teach me, Sir!' Sanatkumâra said to him: 'Please to tell me what you know; afterward I shall tell you what is beyond.'

Nârada said: 'I know the Rig-veda, Sir, the Yagur-veda, the Sâma-veda, as the fourth the Âtharvana, as the fifth the Itihâsa-purâna (the Bhârata); the Veda of the Vedas (grammar); the Pitrya (the rules for the sacrifices for the ancestors); the Râsi (the science of numbers); the Daiva (the science of portents); the Nidhi (the science of time); the Vâkovâkya (logic); the Ekâyana (ethics); the Devavidyâ (etymology); the Brahma-vidyâ (pronunciation, sikshâ, ceremonial, kalpa, prosody, khandas); the Bhûta-vidyâ (the science of demons); the Kshatravidyâ (the science of weapons); the Nakshatra-vidyâ (astronomy); the Sarpa and Devagana-vidyâ (the science of serpents or poisons, and the sciences of the genii, such as the making of perfumes, dancing, singing, playing, and other fine arts). All this I know, Sir.

'But, Sir, with all this I know the Mantras only, the sacred books, I do not know the Self. I have heard from men like you, that he who knows the Self overcomes grief. I am in grief. Do, Sir, help me over this grief of mine.' Sanatkumâra said to him: 'Whatever you have read, is only a name.

'A name is the Rig-veda, Yagur-veda, Sâma-veda, and as the fourth the Âtharvana, as the fifth the Itihâsa-purâna, the Veda of the Vedas, the Pitrya, the Râsi, the Daiva, the Nidhi, the Vâkovâkya, the Ekâyana, the Deva-vidyâ, the Brahma-vidyâ, the Bhûta-vidyâ, the Kshatra-vidyâ, the Nakshatra-vidyâ, the Sarpa and Devagana-vidyâ. All these are a name only. Meditate on the name.

'He who meditates on the name as Brahman, is, as it were, lord and master as far as the name reaches—he who meditates on the name as Brahman.' 'Sir, is there something better than a name?' 'Yes, there is something better than a name.' 'Sir, tell it me.'
