As the body is for the Purusha, Asanas are for Yoga : Misconceptions about Asana Practice
Swadhyaya, or study of the scriptures is an essential component of Yoga. Infact Patanjali enlists Swadhyaya along with Tapas (Austerity) and Ishwara Pranidhana (devotion/surrender to Ishwara) as a core component of Kriya Yoga, or yoga for the busy householder. [Note that Asana is not included here].
Study of the Yogic scriptures makes one a better asana practitioner too because one would learn, then, to sink into the body and let go, instead of grasping to attain photo-perfect poses.
Join me on Sunday Oct. 16 for an overview of the core concepts in the Yoga Sutras.
