Tapas-burning enthusiasm, zeal, sincerity

"Charging all your actions with zeal and sincerity- whether serving family, the greater community, or yourself- transforms them into spiritual practice.  This concept applies to the formal practices as well.  When practicing asana, pranayama, or any of the other practices, the main benefit comes from embracing the deep spiritual intention." - Nischala Joy Devi, The Secret Power of Yoga, p. 213

Imagine there is a rolled towel across your hip points and you are folding over the top of it
Round your back like cat pose- a little bit in all the postures

Intensity, devotion, love, joy
Tapas comes from deep within and is fueled by positivity and love
