Ksana tatkramayoh samyamat vivekajam jnanam
By samyama (uninterrupted atttention of dharana, dhyana and samadhi together) on the moment and on the continuous flow of moments, the yogi gains exalted knowledge, free from the limitations of time and space.
One of the reasons why, as a teacher of asana, I am so intense, and was in the past even harsh, is that I want to give the students one and a half hours of present life in a lesson. As I shout at them to straighten their legs in Sirsasana (headstand), they cannot be wondering what is for dinner or flee the present, one hour's experience of 'now' can be daunting, even exhausting, and I wonder if the fatigue felt by some students after lessons is due more to that than the work of performing asanas. Our perpetual mental absences are like tranquilizing drugs, and the habit dies hard.
