“The Yoga Sūtra is divided into four chapters.
The first chapter called Samādhi Pādaḥ assumes the aspirant
has progressed adequately to be in a state called Samāhita.
Such a person is not easily agitated.
They have a clearer perception to comprehend concepts such as Īśvara and Vairāgya.”
– T Krishnamacharya introduction to Yoga Sūtra Chapter One

“Krishnamacharya taught that a Samāhita Citta
was a prerequisite starting point for Meditation.
If so, how do we relate to the modern phenomenon
that a Vikṣepa Citta can be a starting point for Meditation?
Unless perhaps we discern that here it isn’t actually Meditation?”
