“In Sūtra 1.19 Patañjali appears to be alluding to
two possible cul-de-sac’s for misplaced intention,
in terms of experiencing an illusion of freedom.
What are they and how can they be avoided?”
– Paul Harvey on Yoga Sūtra Chapter One verse 19

“They will, at the proper time of day
and in an appropriate place, sit and
watch the idol until they can completely
recall the image without having to look at it.
This ability will help the person overcome
the distractions from different sources
when they sit for contemplation on Īśvara.”
– T Krishnamacharya on Yoga Sūtra Chapter One verse 42

“Kleśa are not always dominant.
Through Kriyā Yoga they become weaker and weaker.
How is it possible to completely subdue them?
No mental effort can help as Mind is the storehouse of the Kleśa.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 10

‎”When obstacles are present
we must recognise this condition and
develop a means of practice to remove them.”
– TKV Desikachar on Yoga Sūtra Chapter Two verse 11

“Heyaṃ Duḥkham Anāgatam involves two things.
One is owning an acknowledgement of what has
past, in  that what I said or did was out of order
and, at that moment, this was not a skilful action.
The second is anticipation of the future, in that I
need to have acquired some skills to help in creating
new Saṃskāra as potential energetic alternatives.
Both support my efforts to overcome arisings of
old Saṃskāra leading me into re-action, rather
than the intention that I have choices in action.”
– Paul Harvey on Yoga Sūtra Chapter Two verse 16
