Purusha is a complex concept whose meaning evolved in Vedic and Upanishadic times. Depending on source and historical timeline, it means the cosmic being or self, consciousness, and universal principle. In early Vedas, Purusha was a cosmic being whose sacrifice by the gods created all life. This was one of many creation theories discussed in the Vedas. In the Upanishads, the Purusha concept refers to abstract essence of the Self, Spirit and the Universal Principle that is eternal, indestructible, without form and is all pervasive. The Purusha concept is explained with the concept of Prakrti in the Upanishads. The Universe is envisioned in these ancient Sanskrit texts as a combination of the perceivable material reality and non-perceivable, non-material laws and principles of nature. Material reality is everything that has changed, can change and is subject to cause and effect. Purusha is the Universal principle that is unchanging, uncaused but is present everywhere and the reason why Prakrti changes, transforms and transcends all of the time and which is why there is cause and effect. In the RigVeda, "his Puruṣa is all that yet hath been and all that is to be". Purusha is what connects everything and everyone according to the various schools of Hinduism. There is a diversity of views within various schools of Hinduism about the definition, scope and nature of Purusha.
Definition and description
Purusha is a complex concept, whose meaning has diversified over time in the philosophical traditions now called as Hinduism. During the Vedic period, Purusha concept was one of several theories offered for the creation of universe. Purusa, in Rigveda, was described as a being, who becomes a sacrificial victim of gods, and whose sacrifice creates all life forms including human beings. In the Upanishads and later texts of Hindu philosophy, the Purusha concept moved away from the Vedic definition of Purusha and was no longer a person, cosmic man or entity. Instead, the concept flowered into a more complex abstraction. Both Samkhya and Yoga schools of Hinduism state that there are two ultimate realities whose interaction accounts for all experiences and universe - Prakrti and Purusha. In other words, the universe is envisioned as a combination of perceivable material reality and non-perceivable, non-material laws and principles of nature. Material reality, or Prakrti, is everything that has changed, can change and is subject to cause and effect. Universal principle, or Purusha, is that which is unchanging and is uncaused. The animating causes, fields and principles of nature is Purusha in Hindu philosophy. Hinduism refers to Purusha as the soul of the universe, the universal spirit present everywhere, in everything and everyone, all the times. Purusha is Universal Principle that is eternal, indestructible, without form and all pervasive. It is Purusha in the form of nature’s laws and principles that operate in the background to regulate, guide and direct change, evolution, cause and effect. It is Purusha, in Hindu concept of existence, that breathes life into matter, is the source of all consciousness, one that creates oneness in all life forms, in all of humanity, and the essence of Self. It is Purusha, according to Hinduism, why the universe operates, is dynamic and evolves, as against being static. Both Samkhya and Yoga school holds that the path to moksha includes the realization of Purusha.
Related concepts and diversity of views
The abstract idea Purusha is extensively discussed in various Upanishads, and referred interchangeably as Paramatman and Brahman. Sutra literature refers to a similar concept using the word . RishiAngiras of the Atmopanishad belonging to the Atharvaveda explains that Purusha, the dweller in the body, is three-fold: the Bahyatman which is born and dies; the Antaratman which comprehends the whole range of material phenomena, gross and subtle, with which the Jiva concerns himself, and the Paramatman which is all-pervading, unthinkable, indescribable, is without action and has no Samskaras. The Vedanta Sutras state janmādy asya yatah, meaning that 'The Absolute Truth is that from which everything else emanates' Bhagavata Purana .
Theistic schools of Hinduism
There is no consensus among schools of Hinduism on the definition of Purusha, and it is left to each school and individual to reach their own conclusions. For example, one of many theistic traditions script such as Kapilasurisamvada, credited to another ancient Hindu philosopher named Kapila, first describes purusha in a manner similar to Samkhya-Yoga schools above, but then proceeds to describe buddhi as second purusha, and ahamkara as third purusha. Such pluralism and diversity of thought within Hinduism implies that the term purusha is a complex term with diverse meanings.
In one verse of Rigveda, Varna is portrayed as a result of human beings created from different parts of the body of the divinity Purusha. This Purusha Sukta verse is controversial and is believed by many scholars, such as Max Müller, to be a corruption and medieval or modern era insertion into Veda, because unlike all other major concepts in the Vedas including those of Purusha, the four varnas are never mentioned anywhere else in any of the Vedas, and because this verse is missing in some manuscript prints found in different parts of India.
