Conceptual Understanding of Yogasana
The word Yogasana is derived by joining two words that are Yog and Asana.
The word is ‘Yog’derived from the Sanskrit word ‘Yuj’ which means to join together.
The word ‘Asana’ has been derived from the sanskṛta root as meaning ‘To Sit’. This derivative meaning has been used to explain the term physically as well as metaphysically. Physically it denotes a posture or a seat. Metaphysically it has been interpreted by several texts as ‘establishment in the original state’ (svasvarupe samāsannatā-SSP).
The metaphysical aspect of asana is found expressed in the texts of nathayogis like siddha-siddhanta-paddhati, jñānadīpa-bodha, sabadi of yogi vicaranatha. In Jainayoga, asana is considered as withdrawing from parabhava (extraversion) to svabhava (introversion). Acārya haribhadra calls it sukhasana.
In Rajayogarahasya and Trisikhibrahmana (mantra-29) asana is considered as ‘udasinabhava’ meaning “attitude of indifference’.
In kamadhenu-tantra-31 different meanings are attributed to each of the letters in the word asana, ‘a’ meaning atmasamadhu’ (self-realization), ‘sa’ meaning sarvaroga-pratibandhaka’ (preventive of all diseases), and ‘na’ meaning “siddhi prapti (attainment of miraculous powers).
Physically speaking asana has two distinct meanings. Firstly, it denotes the ‘seat’ on which the sadhaka sits for his meditation practice. Secondly, it implies different bodily postures used during yog sadhana.
