Samsara is a grim reaper, but unlike the others, she leads souls not into the afterlife, but their next life. Judging their action while they were alive, she bestows a suitable form upon them as reward or punishment. She is the very embodiment of the endless cycle of reincarnation.
Saṃsāra or Sangsāra (Sanskrit: संसार) (in Tibetan called 'khor ba (pronounced kɔrwɔ [IPA] in many Tibetan dialects) literally meaning "continuous flow", is the repeating cycle of birth, life, death and rebirth (reincarnation) within Hinduism, Buddhism,Taoism, Bön, Jainism, and Yoga. In Sikhism this concept is slightly different and looks at our actions in the present and consequences in the present.
