(Sanskrit) From jiva (जीव living being), and atman (the Being, the Innermost). Originated from the root jīv- 'to breathe'. Jivatman is used to mean the individual soul or essence.
"Jivatman is the individual soul, a reflection of Brahman in Avidya or the mind. Paramatman is the Supreme Soul, Brahman or the Atman. From the empirical viewpoint, the Jivatman is a finite and conditioned being, while the Paramatman is the infinite, eternal, Sat-chit-ananda Brahman. In essence, the Jivatman is identical with Paramatman when Avidya (ignorance) is destroyed." - Sivananda
