Hi everyone,
There is a system of philosophy as part of Hinduism called the Samkhya. This system probably has its origins in the Indus Valley period (pre-vedic) around 2000 BCE.
The individual consciousness called the Purusha, is believe to get bonded or trapped in Prakriti or Nature. Nature has its own set of Laws and rules that cannot be changed by Consciousness. Prakriti gives rise to Intellect (Mahat).....Ahankara (Ego)...Manas (Mind)... and the senses and action related functions.
The Purusha wrongly identifies itself with the Ego and the material world.
As the spirit (Purusha) evolves and develops, it moves upward from the Ego to the Intellect and realizes its true nature as the imperishable one, different from the body and the Ego. This leads to liberation.
Some schools of Samkhya are atheistic in the sense that they don't talk of a God or a creator. But some schools do accept a creator beyond the individual soul.
Samkhya is seen as a twin or as the theory behind the Yoga philosophy that emphasizes the practice.

PS: I have posted it in the Philosophy section because it is it is not about Hindu religion. Eastern philosophy has remained too long as an 'alien' subject segregated as 'Eastern', rather than as a part of world philosophy.
