A key Bhāvana for Samasthiti is on the
relationship of the feet to the ground with
the intention of sensitising the Apāna Sthāna.

We start by activating the soles of the feet
by applying a focused downward pressure.
This helps activate muscle tone in the legs,
and can effect a drop in the sacral area,
and causing a slight lift in the abdomen,
whilst helping to lengthen the lumbar.
All of which is a support and preparation
for focusing on an active exhalation
initiated from the Apāna Sthāna.

You can practice getting people to as if
turn on and turn off the feet and notice
what can happen. Soggy feet implies
both soggy legs and a soggy abdomen.
