- sat (सत्): Being, the true, the absolute.
- cit (चित्): pure consciousness.
- ānanda (आनन्द): bliss, deep joy, pure happiness.
In Indian philosophy, and in Vedānta above all, it names the ultimate nature of reality, of the Absolute (Brahman). The scriptures do not present these three terms as qualities God possesses, but as the very nature of ultimate Reality.
- The major Upaniṣads (Mukhya Upaniṣads) In the oldest texts, written between 800 and 500 BCE, the single compound word « Satcitānanda » does not yet appear. The three ideas are nonetheless constantly brought together, separately, to define Brahman through the celebrated declarations (Mahāvākyas).
-
- Taittirīya Upaniṣad (2.1.1) defines Brahman as:
सत्यं ज्ञानमनन्तं ब्रह्म
(Satyaṁ Jñānam Anantam Brahma)
« Reality/Existence, Knowledge/Consciousness, the Infinite ». Here the word Jñāna, knowledge, corresponds to Cit. - Bṛhadāraṇyaka Upaniṣad (3.9.28) states the link between consciousness and joy explicitly:
विज्ञानमानन्दं ब्रह्म
(Vijñānam Ānandaṁ Brahma)
« Brahman is Consciousness and Beatitude ». - Chāndogya Upaniṣad (6.2.1) insists on the root of Being:
सदेव सोम्येदमग्र आसीदेकमेवाद्वितीयम्
(Sad eva saumya idam agra āsīd ekam evādvitīyam)
« In the beginning, my dear, this world was pure Being (Sat), one without a second ».
- Taittirīya Upaniṣad (2.1.1) defines Brahman as:
- The later Upaniṣads: the compound word appears
The formal fusion of the three terms into a single word, Satcitānanda, appears in later philosophical texts:
-
- Tejobindu Upaniṣad (3.11) holds one of the earliest textual occurrences of the compound. The text proclaims spiritual awakening in these words:
चिद्रूपोऽहं चिदाकाशश्चिदानन्दोऽस्म्यहं तथा । ... सच्चिदानन्दमात्रोऽहं
(Cidrūpo’haṁ cidākāśaścidānando’smyahaṁ tathā | ... Saccidānandamātro’haṁ)
« I am of the nature of consciousness. I am made of consciousness and bliss... I am the One Essence, absolute Consciousness, boundless Beatitude, existence (Sat-Cit-Ānanda). » - Prāṇāgnihotra Upaniṣad uses the same triad to describe the state of one liberated while still living (Jīvanmukta), who realises that their own Self (Ātman) is pure existence, consciousness and bliss.
- Tejobindu Upaniṣad (3.11) holds one of the earliest textual occurrences of the compound. The text proclaims spiritual awakening in these words:
-
- Detachment from the fruits of action (Karma Yoga) purifies action in the physical world (Sat).
- The way of knowledge (Jñāna Yoga) illuminates the mind (Cit).
- The way of devotion (Bhakti Yoga) leads to ecstasy and divine love (Ānanda).
It was then the philosopher Ādi Śaṅkara (eighth century) and the school of non-dual Vedānta (Advaita) who popularised the term Satcitānanda and set it at the summit of Indian theology, to name the state of liberation (Mokṣa).
