Ahamkara is the sense of self or ego in Samkhya philosophy. It is one of the three fundamental principles (gunas) of Samkhya, along with sattva (purity) and tamas (darkness).

Ahamkara is responsible for the sense of individuality, the feeling of 'I', and the feeling of attachment in Samkhya philosophy.

The three fundamental principles (gunas) of Samkhya philosophy are sattva (purity), rajas (activity), and tamas (darkness).

Sattva is the guna responsible for the sense of balance and harmony in Samkhya philosophy.

Rajas is the guna responsible for the sense of activity and passion in Samkhya philosophy.

Tamas is the guna responsible for the sense of inertia and dullness in Samkhya philosophy.

Ahamkara is a product of the three gunas in Samkhya philosophy. The three gunas combine in different proportions to create different types of Ahamkara.

The four types of Ahamkara in Samkhya philosophy are Vaikarika (related to the mind), Taijasa (related to the intellect), Bhutatmaka (related to the five elements), and Sattvika (related to the guna of sattva).

Taijasa Ahamkara is responsible for the sense of self-awareness in Samkhya philosophy.

Vaikarika Ahamkara is responsible for the sense of individuality in Samkhya philosophy.

Bhutatmaka Ahamkara is responsible for the sense of attachment to the body and the material world in Samkhya philosophy.

Sattvika Ahamkara is responsible for the sense of purity and discrimination in Samkhya philosophy.

The goal of Samkhya philosophy is to achieve liberation from the cycle of birth and rebirth, to attain the state of pure consciousness, and to realize the true nature of reality.

Samkhya philosophy views the relationship between the self and the world as interdependent. The self is the conscious principle, while the world is the material principle. The two are interdependent, as the self needs the world to experience itself, and the world needs the self to be conscious.

In Samkhya philosophy, Ahamkara must be transformed in order to achieve liberation. This transformation involves recognizing the true nature of the self and realizing that the self is not the ego or the sense of 'I'.
