Avidya is the term used in Samkhya Philosophy to describe the fundamental ignorance or lack of discrimination that obscures the true nature of reality.

According to Samkhya Philosophy, Avidya is caused by attachment to the material world, desire for sense objects, and egoism.

In Samkhya Philosophy, Avidya is considered to be both positive and negative. It is positive in the sense that it is a creative force that gives rise to the phenomenal world. However, it is also negative in the sense that it obscures the true nature of reality.

In Samkhya Philosophy, Avidya leads to suffering, prevents the individual from realizing their true nature, and causes the individual to identify with the ego.

The goal of Samkhya Philosophy is to eliminate Avidya and achieve liberation from suffering.

According to Samkhya Philosophy, Avidya can be eliminated through knowledge and discrimination, meditation and yoga, and selfless action.
