Satcitananda is a Sanskrit word that is often translated as "existence, consciousness, bliss" or "reality, consciousness, bliss". It is a central concept in Hinduism and Vedanta philosophy, and it is seen as the ultimate nature of reality.

Sat refers to existence, which is the fundamental truth that everything exists. It is the unchanging, eternal reality that underlies all phenomena.

Cit refers to consciousness, which is the awareness or sentience that is present in all beings. It is the fundamental light or intelligence that illumines all things.

Ananda refers to bliss, which is the supreme state of happiness and fulfillment. It is the ultimate satisfaction that arises from the realization of one's true nature as sat-cit-ananda.

Satcitananda is often represented as a divine trinity, with Brahma representing existence, Vishnu representing consciousness, and Shiva representing bliss. These deities are seen as different aspects of the same ultimate reality.

The concept of satcitananda is central to the Hindu concept of moksha, which is the liberation from the cycle of rebirth and suffering. Moksha is achieved through the realization of one's true nature as sat-cit-ananda.

In Vedanta philosophy, satcitananda is identified with the Brahman, which is the ultimate reality or absolute truth. Brahman is seen as the ground of all existence, consciousness, and bliss.

Satcitananda is also a concept that is found in other spiritual traditions, such as Buddhism and Taoism. In Buddhism, the concept of emptiness (shunyata) is seen as closely related to satcitananda. In Taoism, the concept of the Tao is seen as the embodiment of satcitananda.

Satcitananda is a profound and complex concept that has been interpreted in many different ways. However, it is ultimately a way of understanding the ultimate nature of reality and the path to liberation from suffering.
