Sat-Chit-Ananda

Satchitananda (IAST: Satcitānanda) or Sacchidānanda representing "existence, consciousness, and bliss" or "truth, consciousness, bliss", is an epithet and description for the subjective experience of the ultimate, unchanging reality in Hinduism called Brahman.

Satchitananda (Sanskrit: सच्चितानन्द) is a compounded Sanskrit word consisting of "sat", "cit" and "ananda", all three considered as inseparable from the nature of ultimate reality called Brahman in Hinduism. The different forms of spelling is driven by euphonic (sandhi) rules of Sanskrit, useful in different contexts.

Satchitananda is therefore translated as "Truth Consciousness Bliss", "Reality Consciousness Bliss", "Existence Consciousness Bliss",

The term is contextually related to "the ultimate reality" in various schools of Hindu traditions. In theistic traditions, sacchidananda is same as God such as Vishnu, Shiva or Goddess in Shakti traditions. In monist traditions, sacchidananda is considered directly inseparable from nirguna (attributeless) Brahman or the "universal wholeness of existence", wherein the Brahman is identical with Atman, the true individual self.Satchitananda or Brahman is held to be the source of all reality, source of all conscious thought, and source of all perfection-bliss. It is the ultimate, the complete, the destination of spiritual pursuit in Hinduism.

The Brihadaranyaka Upanishad (c. 800–600 BCE) is among the earliest Hindu texts which links and then discusses Atman (soul), Brahman (ultimate reality), awareness, joy and bliss such as in sections 2.4, 3.9 and 4.3. The Chandogya Upanishad (~800-600 BCE), in section 3.14 to 3.18, discusses Atman and Brahman, these being identical to "that which shines and glows both inside and outside", "dear", "pure knowing, awareness", "one's innermost being", "highest light", "luminous". Other 1st-millennium BCE texts, such as the Taittiriya Upanishad in section 2.1, as well as minor Upanishads, discuss Atman and Brahman in saccidananda-related terminology.

An early mention of the compound word sacchidananda is in verse 3.11 of Tejobindu Upanishad, composed before the 4th-century CE. The context of sacchidananda is explained in the Upanishad as follows:

The realization of Atman.

(...) I am of the nature of consciousness.
I am made of consciousness and bliss.
I am nondual, pure in form, absolute knowledge, absolute love.
I am changeless, devoid of desire or anger, I am detached.
I am One Essence, unlimitedness, utter consciousness.
I am boundless Bliss, existence and transcendent Bliss.
I am the Atman, that revels in itself.
I am the Sacchidananda that is eternal, enlightened and pure.
