Sanskrit grammar in the context of "Declension"

Guru (/ˈɡuːruː/ Sanskrit: गुरु; IAST: guru) is a Sanskrit term for a "mentor, guide, expert, or master" of certain knowledge or field. In pan-Indian traditions, a guru is more than a teacher: traditionally, the guru is a reverential figure to the disciple (or shisya in Sanskrit, literally seeker [of knowledge or truth]) or student, with the guru serving as a "counsellor, who helps mould values, shares experiential knowledge as much as literal knowledge, an exemplar in life, an inspirational source and who helps in the spiritual evolution of a student". Whatever language it is written in, Judith Simmer-Brown says that a tantric spiritual text is often codified in an obscure twilight language so that it cannot be understood by anyone without the verbal explanation of a qualified teacher, the guru. A guru is also one's spiritual guide, who helps one to discover the same potentialities that the guru has already realized.

The oldest references to the concept of guru are found in the earliest Vedic texts of Hinduism. The guru, and gurukula – a school run by guru, were an established tradition in India by the 1st millennium BCE, and these helped compose and transmit the various Vedas, the Upanishads, texts of various schools of Hindu philosophy, and post-Vedic Shastras ranging from spiritual knowledge to various arts so also specific science and technology. By about mid 1st millennium CE, archaeological and epigraphical evidence suggest numerous larger institutions of gurus existed in India, some near Hindu temples, where guru-shishya tradition helped preserve, create and transmit various fields of knowledge. These gurus led broad ranges of studies including Hindu scriptures, Buddhist texts, grammar, philosophy, martial arts, music and painting.

Shabda (Sanskrit: शब्द, IAST: Śabda) is the Sanskrit word for "speech sound". In Sanskrit grammar, the term refers to an utterance in the sense of linguistic performance.

Sanskrit has been studied by Western scholars since the late 18th century. In the 19th century, Sanskrit studies played a crucial role in the development of the field of comparative linguistics of the Indo-European languages. During the British Raj (1857–1947), Western scholars edited many Sanskrit texts which had survived in manuscript form. The study of Sanskrit grammar and philology remains important both in the field of Indology and of Indo-European studies.

Citta (Pali and Sanskrit: चित्त, or in Prakrit script 𑀘𑀺𑀢𑁆𑀢, pronounced chitta [t͡ɕit̚.tɐ́]) is one of three overlapping terms used in the Nikaya to refer to the mind, the others being manas and viññāṇa. Each is sometimes used in the generic and non-technical sense of "mind" in general, and the three are sometimes used in sequence to refer to one's mental processes as a whole. However, their primary uses are distinct.

Mahabhashya (Sanskrit: महाभाष्य, IAST: Mahābhāṣya, IPA: [mɐɦaːbʱaːʂjɐ], "Great Commentary"), attributed to Patañjali, is a commentary on selected rules of Sanskrit grammar from Pāṇini's treatise, the Aṣṭādhyāyī, as well as Kātyāyana's Vārttika-sūtra, an elaboration of Pāṇini's grammar. It is dated to the 2nd century BCE.

Vṛddhi (also rendered vr̥ddhi) is a technical term in morphophonology given to the strongest grade in the vowel gradation system of Sanskrit and of Proto-Indo-European. The term is derived from Sanskrit वृद्धि vṛddhi, IPA: [ˈʋr̩d̪̚.d̪ʱi], lit. 'growth', from Proto-Indo-European *werdʰ- 'to grow'.
