We must also consider the safety factors

3. For example Viparīta Padmāsana could
be approached by working dynamically
from Ardha Padma Sarvāṅgāsana
into Ardha Padma Halāsana. This would
ascertain the ability to work into and with
Padmāsana in an inverted Āsana such as Śīrṣāsana.
Thus, any Āsana practice must allow for certain
safety factors, so we are able to work with respect
and regard for the individual involved and yet
retain consideration of and for the safety factors.
