One aspect to the art of modification in Āsana,
is in order to sustain a specific direction of Candra
according to the primary Lakṣaṇa of and in an Āsana,
amidst a contrary potential to stimulate a dispersion
of Candra, because of the demands of the secondary
Lakṣaṇa overpowering that of the primary Lakṣaṇa.
This also implies that we have personally embedded
a theoretical and experiential understanding, through
study of the process in the Viniyoga of Āsana, according
to their inherent primary and secondary characteristics.
