The concept of Karma is based on the belief that every action, whether good or bad, has consequences that will eventually come back to the individual who performed it.

Sanchita Karma refers to the sum total of all the actions performed by an individual in their past lives. Prarabdha Karma is the portion of Sanchita Karma that is currently being experienced in the present life. Kriyamana Karma refers to the actions being performed in the present life that will have consequences in future lives.

According to Indian philosophy, the actions performed in one life determine the individual's next life. Good actions lead to a better rebirth, while bad actions lead to a worse rebirth.

The ultimate goal of Karma is to achieve liberation from the cycle of rebirth, also known as moksha or nirvana. This can be achieved through spiritual practices and ethical conduct.

An individual can improve their Karma by performing good deeds, such as helping others, being honest, and living a virtuous life. Avoiding bad deeds, such as harming others, lying, and stealing, is also important for improving Karma.

Karma is determined by the actions that an individual chooses to perform. Free will allows individuals to make choices that will have consequences in their present and future lives.

Karma is partially deterministic because it is influenced by the actions that an individual has performed in the past. However, it is not completely deterministic because individuals have the free will to choose their actions in the present, which can shape their future Karma.

Karma is a part of Dharma, which is the broader concept of ethical and moral conduct in Indian philosophy. Dharma encompasses not only individual actions but also social and cosmic order.

Karma is often used in Indian society to promote social harmony by encouraging individuals to perform good deeds and avoid bad deeds. The belief in Karma can help to create a sense of moral responsibility and encourage people to live in a way that benefits both themselves and others.

The concept of Karma has been criticized by some philosophers and scholars who argue that it is simplistic, deterministic, and does not take into account the complexity of human behavior and the influence of external factors on an individual's life.

The concept of Karma has been criticized for being too simplistic, deterministic, fatalistic, and for being used to justify social inequalities and oppression.

Some philosophers have responded to the criticisms of the concept of Karma by modifying it to address the concerns raised. For example, they may argue that Karma is not deterministic but rather probabilistic, or that it is not fatalistic but rather encourages individuals to take responsibility for their actions.

The concept of Karma is still widely accepted and practiced in contemporary Indian thought. It continues to influence ethical decision-making, social interactions, and religious beliefs among many Indians.

The concept of Karma is closely related to the concepts of Dharma, Moksha, and Samsara in Indian philosophy. Dharma refers to ethical and moral conduct, Moksha refers to liberation from the cycle of rebirth, and Samsara refers to the cycle of birth, death, and rebirth.

Studying the concept of Karma presents several challenges, including the lack of empirical evidence, the diversity of interpretations of the concept, and the influence of cultural and religious beliefs.
