Dualism (Indian philosophy) in the context of "Samkhya"

Hindu philosophy or Vedic philosophy is the set of philosophical systems that developed in tandem with the first Hindu religious traditions during the iron and classical ages of India. In Indian philosophy, of which Hindu philosophy is a prominent subset, the word used for philosophy is Darshana (Sanskrit: दर्शन; meaning: "viewpoint or perspective"), from the Sanskrit root 'दृश' (drish) meaning 'to see, to experience'.

The schools of thought or Darshanas within Hindu philosophy largely equate to the six ancient orthodox schools: the āstika (Sanskrit: आस्तिक) schools, defined by their acceptance of the Vedas, the oldest collection of Sanskrit texts, as an authoritative source of knowledge. Of these six, Samkhya (सांख्य) is the earliest school of dualism; Yoga (योग) combines the metaphysics of Samkhya with meditation and breath techniques; Nyaya (न्याय) is a school of logic emphasising direct realism; Vaisheshika (वैषेशिक) is an offshoot of Nyaya concerned with atomism and naturalism; Mimamsa (मीमांसा) is a school justifying ritual, faith, and religious obligations; and Vedanta (वेदान्त) contains various traditions that mostly embrace nondualism.

In Hinduism, the conception of God varies in its diverse religio-philosophical traditions. Hinduism comprises a wide range of beliefs about God and divinity, such as henotheism, monotheism, polytheism, panentheism, pantheism, pandeism, monism, agnosticism, atheism, and nontheism.

Forms of theism find mention in the Bhagavad Gita. Emotional or loving devotion (bhakti) to a primary god such as avatars of Vishnu (Krishna for example), Shiva, and Devi (as emerged in the early medieval period) is now known as the Bhakti movement. Contemporary Hinduism can be categorized into four major theistic Hindu traditions: Vaishnavism, Shaivism, Shaktism, and Smartism. Vaishnavism, Shaivism, and Shaktism worship the Hindu deities Vishnu, Shiva, and Devi as the Supreme God respectively, or consider all Hindu deities as aspects of the same, Supreme Reality or the eternal and formless metaphysical Absolute, called Brahman in Hinduism, or, translated from Sanskrit terminology, Svayaṁ-Bhāgavan ("God Itself"). Other minor sects such as Ganapatya and Saura focus on the deities Ganesha or Surya as the Supreme.

Yoga philosophy is one of the six major important schools of Hindu philosophy, though it is only at the end of the first millennium CE that Yoga is mentioned as a separate school of thought in Indian texts, distinct from Samkhya. Ancient, medieval and modern literature often simply call Yoga philosophy Yoga. A systematic collection of ideas of Yoga is found in the Yoga Sutras of Patanjali, a key text of Yoga which has influenced all other schools of Indian philosophy.

The metaphysics of Yoga is Samkhya's dualism, in which the universe is conceptualized as composed of two realities: Puruṣa (witness-consciousness) and Prakṛti (nature). Jiva (a living being) is considered as a state in which puruṣa is bonded to Prakṛti in some form, in various permutations and combinations of various elements, senses, feelings, activity and mind. During the state of imbalance or ignorance, one or more constituents overwhelm the others, creating a form of bondage. The end of this bondage is called liberation, or mokṣa, by both the Yoga and Samkhya schools of Hinduism, and can be attained by insight and self-restraint.

Shaiva Siddhanta (IAST: Śaiva-siddhānta) (Tamil: சைவ சித்தாந்தம் "Caiva cittāntam") is a form of Shaivism from South India and Sri Lanka that propounds a dualistic philosophy where the ultimate and ideal goal of a being is to become an enlightened soul through Shiva's grace. It draws primarily on the Tamil devotional hymns written by Shaiva saints from the 5th to the 9th century, known in their collected form as Tirumurai. Meykandadevar (13th century) was the first systematic philosopher of the school. The normative rites, cosmology and theology of Shaiva Siddhanta draw upon a combination of Agamas and Vedic scriptures.

This tradition is thought to have been once practiced all over Greater India, but the Muslim subjugation of North India restricted Shaiva Siddhanta to the south where it merged with the Tamil Shaiva movement expressed in the bhakti poetry of the Nayanars which was the first reaction against the nastika philosophies. Today, Shaiva Siddhanta has adherents predominantly in South India and Sri Lanka, and in a Tantrayana syncretised form in Indonesia (as Siwa Siddhanta).

Lila (Sanskrit: लीला līlā) or leela (/ˈliːlə/) can be loosely translated as "divine play". The concept of lila asserts that creation, instead of being an objective for achieving any purpose, is rather an outcome of the playful nature of the divine. As the divine is perfect, it could have no want fulfilled, thereby signifying freedom, instead of necessity, behind the creation.

The concept of lila is common to both non-dualist and dualist philosophical schools of Indian philosophy, but has a markedly different significance in each. Within non-dualism, lila is a way of describing all reality, including the cosmos, as the outcome of creative play by the divine absolute (Brahman). In Vaishnavism, lila refers to the activities of God and devotee, as well as the macrocosmic actions of the manifest universe.
