Answer:
Moksha=ultimate spiritual goal
Atman=Soul
Samsara=Cycle of birth and death
Step-by-step explanation:
Atman literally means soul in Sanskrit, and is used in hinduism to describe someone's true self, or soul.
Moksha is the release, the liberation, or the end to the cycle of reincarnation, and the ultimate goal of a Hindu or Buddhist.
Samsara is the central concept of reincarnation. The soul(atman) is awash in the sea of samsara and seeks to achieve moksha to free itself of its past deeds.
