“Another simple posture is Adho Mukha Śvan Āsana.
the next step is to try them in some sitting postures such as Mahā Mudrā.
These Bandha can also be done in the headstand.
It is easy to do Bandha in this position because the lifting,
Uḍḍīyana Bandha, and holding up, Mūla Bandha,
of Apāna to the flame is almost automatic
because now the Apāna is above the flame.
If we can do the three Bandha in these postures,
we are ready to introduce them in our Prāṇāyāma.”
– TKV Desikachar ‘The Concept, Preparation and Techniques of Bandha’
Religiousness in Yoga Chapter Fourteen Page 197

“Another important thing that he has understood is
that these Āsana should not be taken one by one,
they have to be taken as a group and as a composition.
This means you don’t do headstand on Monday,
shoulder stand on Tuesday,
you do your group of Āsana linked like words in a sentence.”
– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.

“Five questions my teacher taught me that need to be ‘posed’,
for or to any student wishing to practice Śīrṣāsana,
or even for and to any teacher wishing to teach Śīrṣāsana,
whatever the situation.

1. Who is going to practice it?
2. Why do they wish to use it?
3. When are they going to practice it?
4. How are they going to get in and out of it?
5. What do they need to have done to verify their capability?”
