Commentaries and ReflectionsT Krishnamacharya:
All mental distractions arise from the free play of the senses
and only through continuing practice can one keep their power in check.

in addition, leads to the acquisition of still more Saṃskāra.
Samādhi is a state of mind and an understanding that arises from it.Paul Harvey:
Other than this is the practice where only tendencies remain,
it is preceded by the cessation of psychic activity.
