Philosophy is a belief (or system of beliefs) that deal with the rational investigation of questions about existence and knowledge and ethics. There are six schools of philosophy developed in India with the beginning of the Christian era such as 1) Yoga, 2) Nyaya, 3) Mimamsa, 4) Vedanta, 5) Vaisheshikha and 6) Samkhya. The exact dates of formalizing the six systems are not known, as the studies were originally purely oral, since writing had not yet been created. However, estimates generally range from about 2,000-3,000 or more years ago. Some say the roots of these are as much as 5,000-10,000 years ago, or more.
Samkhya literally means count. The Samkhya philosophy states that:
1. The world is created by Nature or Prakriti
2. Around the fourth century AD, Purusha was added and the creation of the world was attributed both to Nature and the Purusha
3. As per the Samkhya School of philosophy, salvation can be attained by a person through the acquisition of real knowledge and his misery can come to an end.The real knowledge can be obtained through Anumana (inference), Shabda (hearing) and Pratyaksha (perception)
