Abstract: Na hi kaścit kṣaṇamapi jātu tiṣṭhatyakarmakṛt(3/5) –according to Bhagavadgītā one cannot exist a single moment without doing karma. Karma in its simplest term is ‘action’only. But according to Indian philosophy, the word karma has a much greater significance than just simple meaning as ‘action’. As per the Indian Philosophy, any action that we do, produce some fruits or has a consequences. Upaniṣads say, if one sows goodness, will reap goodness; if one sows evil,will reap evil. In the Upaniṣads there are primarily three kinds of karma– prārabdha Karma, sañcita Karma and kriyamāna Karma. Every living being has to live through these three types of karma. Because the ultimate characteristic of the body in which the living being born is karma. From birth to death, and even the state after death, a living being is determined by this karma.The Upaniṣads describe three state of life after death,depending on the action of the Jīva: the path of the Devayāna for the Saguṇa Brahmins, the path of the Pitṛyāna for the one who performs Vedic rituals, and the third state for the lower beings.
