BrahmanIn Hinduism, Brahman (ब्रह्मन्) connotes the highest universal principle, the ultimate reality in the universe. In major schools of Hindu philosophy, it is the immaterial, efficient, formal and final cause of all that exists. It is the pervasive, infinite, eternal truth, consciousness and bliss which does not change, yet is the cause of all changes. Brahman as a metaphysical concept refers to the single binding unity behind diversity in all that exists in the universe.
Guṇa(गुण) is a concept in Hinduism and Sikhism, which can be translated as "quality, peculiarity, attribute, property". The concept is originally notable as a feature of Samkhya philosophy. The guṇas are now a key concept in nearly all schools of Hindu philosophy. There are three guṇas, according to this worldview, that have always been and continue to be present in all things and beings in the world. These three guṇas are called: (goodness, calmness, harmonious), (passion, activity, movement), and (ignorance, inertia, laziness).
Tamas (philosophy)Tamas (Sanskrit: तमस् tamas, darkness) is one of the three guṇas (tendencies, qualities, attributes), a philosophical and psychological concept developed by the Samkhya school of Hindu philosophy. The other two qualities are rajas (passion and activity) and sattva (purity, goodness). Tamas is the quality of inertia, inactivity, dullness, or lethargy. The Vedic word támas refers to "darkness" and the Indo-European word *temH-es, meaning "dark", and the Lithuanian word tamsa, meaning "darkness", is related to it.
RajasRajas (Sanskrit: रजस्) is one of the three guṇas (tendencies, qualities, attributes), a philosophical and psychological concept developed by the Samkhya school of Hindu philosophy. The other two qualities are sattva (goodness, balance) and tamas (lethargy, violence, disorder). Rajas is innate tendency or quality that drives motion, energy and activity. Rajas is sometimes translated as passion, where it is used in the sense of activity, without any particular value and it can contextually be either good or bad.
Bhagavad GitaThe Bhagavad Gita (ˌbʌɡəvəd_ˈɡiːtɑː; भगवद्गीता), often referred to as the Gita (), is a 700-verse Hindu scripture, which is part of the epic Mahabharata. It forms the chapters 23–40 of book 6 of the Mahabharata called the Bhishma Parva. The work is dated to the second half of the first millennium BCE. Typical of the Hindu synthesis, it is considered one of the holy scriptures of Hinduism. The Bhagavad Gita is set in a narrative framework of dialogue between the Pandava prince Arjuna and his charioteer guide Krishna, an avatar of lord Vishnu.
SamkhyaSamkhya or Sankya (ˈsɑːŋkjə; sāṃkhya) is a dualistic orthodox school of Hindu philosophy. It views reality as composed of two independent principles, Puruṣa ('consciousness' or spirit) and Prakṛti (nature or matter, including the human mind and emotions). Puruṣa is the witness-consciousness. It is absolute, independent, free, beyond perception, above any experience by mind or senses, and impossible to describe in words. Unmanifest Prakriti is matter or nature.
IshvaraIshvara (ईश्वर) is a concept in Hinduism, with a wide range of meanings that depend on the era and the school of Hinduism. In ancient texts of Hindu philosophy, depending on the context, Ishvara can mean supreme Self, ruler, lord, king, queen or husband. In medieval era Hindu texts, depending on the school of Hinduism, Ishvara means God, Supreme Being, personal God, or special Self. Ishvara is primarily an epithet of Shiva. In Shaivism, Ishvara is an epithet of Shiva.
Yoga (philosophy)Yoga philosophy is one of the six major orthodox schools of Hinduism, 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 most modern literature often refers to Yoga-philosophy simply as 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.
ShaktiIn Hinduism, Shakti (Devanagari: शक्ति, IAST: Śakti; lit. "Energy, ability, strength, effort, power, capability") is the fundamental cosmic energy and a central deity within Shaktism, a significant theological tradition of Hinduism. Representing dynamic forces that permeate the universe, Shakti embodies feminine energy and is often depicted as the consort of Shiva. In this tradition, Devi, the Goddess, is regarded as the Supreme Brahman herself, with all other divine forms seen as her manifestations.
PurushaPurusha (पुरुष, ) 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, awareness, 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 myths discussed in the Vedas. In the Upanishads, the Purusha concept refers to the abstract essence of the Self, Spirit and the Universal Principle that is eternal, indestructible, without form, and is all-pervasive.
