Karma (literally "action") is the universal law of cause and effect in Hindu philosophy. Every action — physical, mental, or verbal — creates a karmic imprint (samskara) that influences future experiences. There are three types of Karma: Sanchita (accumulated karma from all past lives), Prarabdha (portion of Sanchita karma that is currently active), and Kriyamana/Agami (karma being created by present actions). The Bhagavad Gita teaches three approaches to Karma: Karma Yoga (selfless action without attachment to results), Nishkama Karma (desireless action), and Sakama Karma (action with desire). Good karma leads to favorable births and circumstances; bad karma leads to suffering. Liberation (Moksha) is achieved when all karmic debts are resolved. The concept is closely linked to Samsara (cycle of rebirth).
