“In Āyurveda, it gives certain behaviour by which we can stay well.
If a person follows the following he will freer of sickness.
Regularly, systematically he eats, rests and exercises adequately.
Both in amount and quality.
Food or Āhāra, along with Vihāra – recreation, rest, exercise, other activities.”
– TKV Desikachar France 1983

“Within the teachings of T Krishnamacharya,
as transmitted to TKV Desikachar,
the role of Śavāsana within an Āsana practice was as
a transitional link pose between categories of Āsana.
For example between Standing and Lying Āsana,
or Lying and Inverted Āsana,
or Inverted and Prone Backbends,
or Prone Backbends and Seated Āsana,
or Seated Āsana and Sitting Practices.
The extent of its use and length of rest at each stage,
when transiting from one category to another within our
Āsana practice journey, was dependent on the facility
of the practitioner and the intensity of the practice.
Within this individualised variance is the guiding
principle that the role of Śavāsana is to facilitate a
smooth transition for the flow of the breath and also
the pulse through and beyond the Āsana practice,
as a marker for the practitioner’s state of mind.
However according to Desikachar the Viniyoga of
Śavāsana was seen in terms of recovery from the
fatigue of the preceding aspect of the practice rather,
than say recovery from the preceding aspects of one’s life.
Regarding the approach for the recovery
from the preceding aspects of one’s life,
amongst other things such as Āhāra and Vihāra,
the wider purpose, content, duration and frequency
of the Āsana practice must be carefully reconsidered.”
