The expression, sam nah bhavatu, may he be blissful to us, is to be connected with all. These are the deities in the context of the body. Visnu is urukramah, possessed of great strides, and identifies himself with the feet. Aryaman identifies himself with the eye and the sun, Indra with strength, and Brhaspati with speech and intellect. Similarly, too, Varuna is the deity who identifies himself with and is the self of the function of inhaling and of night. May Mitra, the deity who identifies himself with and is the self of the function of exhaling and of day become sam, blissful nah, to us. You alone I shall call the direct Brahman. May Vishnu, of long strides, be blissful to us. May Indra and Brihaspati be blissful to us.

Shanti Mantra This edition uses English transalation of the Upanishad with Shankaracharya's commentary translated by Swami Gamhirananda. The third chapter Bhrigu Valli consists of 10 Anuvakas 15 verses (1st to 9th 1 verse each, 10th - 6 Verses). The second chapter Ananda Valli, sometimes called Brahmananda Valli includes 9 Anuvakas 13 verses (1st to 7th and 9th contains 1 verse each, 8th contains 5 Verses). The Taittiriya Upanishad has three chapters:- The first chapter Siksha Valli includes 12 Anuvaka (lessons) 23 verses (1st, 2nd, 7th, 8th, 9th, 10th, and 12th each contains 1 verse 3rd - 4 Verses, 4th - 3 verses, 5th - 3 Verses, 6th - 2 verses, and 11th - 4 Verses). The Bhrigu Valli describes how son of Varuna (The Water God) Bhrigu obtained realization of Brahman through repeated Tapas under his fathers guidance. The Brahmananda Valli teaches about Brahman and tries to define it as "Truth, Omniscient, and Infinite". The Siksha Valli deals with the discipline of Shiksha (which is the first of the six Vedangas or "limbs" or auxiliaries of the Vedas), that is, the study of phonetics and pronunciation. It is divided into three sections, 1) the Siksha Valli, 2) the Brahmananda Valli and 3) the Bhrigu Valli. The Taittiriya Upanishad says that the highest goal is to know the Brahman, for that is truth. The inner Self is constituted by pure happiness (ananda)." (2.5.1) The Self (Atman) is part of the Ancient and remains in it through knowledge even when it incarnates in a body. It is in knowledge that the Devas meditate on Brahman by knowing it without misunderstandings all the negative reactions are destroyed and one fully enjoys all good things. "Knowledge (vijnana) is the fundamental ingredient of sacrifice (yajna) and the performance of one's duties (karmani). After an invocation to Mitra, Varuna, Aryaman, Indra, Brihaspati and Vishnu Trivikrama, the first verse addresses Vayu as the direct manifestation of Brahman, Dharma and Satya, asking for his protection.
