The Taittiriya Upanishad Dhyana Mantra refers to the meditative verses found within the Taittiriya Upanishad, which is part of the Krishna Yajurveda. This Upanishad is divided into three sections: the Samhita Upanishad, the Brahmananda Valli, and the Bhrigu Valli. The dhyana mantras are primarily associated with the Brahmananda Valli, which expounds the five sheaths (pancha-kosha) covering the Atman: annamaya (food), pranamaya (vital air), manomaya (mind), vijnanamaya (intellect), and anandamaya (bliss). The text declares in Taittiriya Upanishad 2.5, 'Anando brahmeti vyajanat' (Bliss is Brahman), establishing the ultimate reality as bliss.
The mantra 'Satyam jnanam anantam brahma' (Taittiriya Upanishad 2.1) describes Brahman as truth, knowledge, and infinity. The beej-akshara 'Om' is often prefixed to these mantras, as per Vedic tradition. The purpose of chanting these dhyana mantras is to facilitate meditation on the layers of the self, leading to the realization of the Atman as distinct from the koshas and ultimately identical with Brahman. Traditional benefits include purification of the mind, deepening of self-inquiry (atma-vichara), and attainment of liberation (moksha).
According to the commentary of Shankaracharya on the Taittiriya Upanishad, these mantras are chanted during study of Vedanta, especially in the morning or during meditation sessions. The recommended count is 108 repetitions (japa) daily, or as part of a structured Upanishad recitation. There are no specific cautions, but tradition holds that one should approach these mantras with reverence and a qualified teacher (guru) for proper understanding. The Taittiriya Upanishad is also cited in the Brahma Sutras (1.1.12-19) as a key source for the nature of Brahman.
The dhyana mantras thus serve as a profound tool for self-realization, guiding the practitioner through the koshas to the blissful core of existence.
Om. Brahman is truth, knowledge, and infinity.
The mantra begins with the seed-syllable 'Om', which is the primordial beej-akshara representing Brahman. No other seed-syllables are present.
