Commentaries and Reflections

Commentary by T Krishnamacharya:

“The practice of Āsana without breathing and
without remembering Ananta has no value.”

Commentary by TKV Desikachar:

“The test for intelligent effort
is the response of the Breath.”

Commentary by Paul Harvey:

“The experience known as Sthira Sukham Āsanam,
described in Yoga Sūtra Chapter Two verse 46,
arises as a fruit of Yoga Sūtra Chapter Two verse 47,
from melding the mastery of outer stillness in the world,
described as Prayatna Śaithilya, or relaxation of continued effort,
with the mystery of inner openness to the beyond,
described as Ananta Samāpatti, or unity in the infinite.”

“Our continued effort
with the breath in Āsana
is that which helps to enliven
our various levels of interaction
with our inner and outer worlds as
expressed through the Pañca Maya.”

“Two primary roles in the adaptation of Āsana
to the needs and potential of the student are:
Facilitating a decrease of tension within the body
whilst
Facilitating an increase of attention within the breath.”
