Here at once should be noted, that although in Hindu theology we find Brahma, Vishnu and Siva, as the creator, preserver and destroyer, forming the Trinity, the Upanishad now before us—for cutting away error—has not such a division. It says Brahma is first, also the maker and the preserver. Even knowledge that is true for certain stages of development becomes error when we rise up into the higher planes and desire to know the true. Similarly we find Buddha in his congregation teaching his disciples by means of the “three vehicles,” but when he had raised them to the higher plane, he informed them that these vehicles might be discarded and _sat_ or truth be approached through one vehicle. The knowledge here spoken of is Brahman knowledge which is the supreme vehicle. “2. Whatever Brahma told Atharvan that knowledge Atharvan told to Angir, he told it to Satyavaha Bharadvaga, and he in succession told it to Angiras. “3. Saunaka, the great householder, approached Angiras respectfully and asked ‘Sir, what is that through which if it is known, everything else becomes known?’ “4. He said to him: ‘Two kinds of knowledge must be known, this is what all who know Brahman tell us, the higher and the lower knowledge. “5. ‘The lower knowledge is the Rig-Veda, Yajur-Veda, Sama-Veda, Atharva-Veda Phonetics, Ceremonial, Grammar, Etymology, Metre and Astronomy; but the higher knowledge is that by which the Indestructible (Brahma) is apprehended. “6. ‘That which cannot be seen nor seized, which has no origin and is without qualities, no eyes nor ears, no hands nor feet, the eternal, the all pervading, infinitesimal, that which is imperishable, that is what is regarded by the wise as the source of all beings. “7. ‘As the spider sends forth and draws in its thread, as plants grow on the earth, as from every man hairs spring forth on the head and the body, thus does everything arise here from the Indestructible. “8. ‘The Brahman swells by means of meditation; hence is produced matter; from matter mind, breath and intellect, the seven worlds, and from the works performed by men in the worlds, the eternal effects, rewards and punishment of works. “9. ‘From Him who perceives all and who knows all, whose meditation consists of knowledge, from that highest Brahman is born that other Hiranyagarbha—name, form, and matter.’”
