Surya Namaskara (Sanskrit: सूर्यनमस्कार, IPA: [suːrjɐ nɐmɐskɐːrɐ]; IAST: Sūrya Namaskāra) is a common sequence of asanas. Its origins lie in India where its large Hindu population worships Surya, the Hindu solar deity. This sequence of movements and asanas can be practised on varying levels of awareness, ranging from that of physical exercise in various styles, to a complete sadhana which incorporates asana, pranayama, mantra and chakra meditation. It is often the beginning vinyasa within a longer yoga series. Sūrya Namaskāra may also refer to other styles of "Salutations to the Sun". The Sun Salutation is regularly practised in many Indian schools.
The Hatha Yoga Pradipika, the oldest known hatha yoga text does not mention "Surya namaskar" but mentions a sūrya-bhedana (sun-piercing) kumbhaka (II, 44 and 48–50) while the Gheraṇḍa Saṁhitā mentions sūrya-bheda kumbhaka (58–59). The oldest documented book with clear depictions of asanas is the Sritattvanidhi, though there is no mention of Surya namaskar in the text, it does describe the asanas "Sarpasana" (Bhujangasana), "Gajasana" (Adhomukh Swannasan), "Uttanasana" and series of asanas done in tandem, similar to Sūrya Namaskāra..
