“Taking care within the ‘small‘ arisings
is directly related to our capacity to
take care within the ‘big‘ arising.”
– Paul Harvey on Yoga Sūtra Chapter Two verse 2

“All these Kleśa are variable in their potency.
They can be so weak, that they hardly matter.
Sometimes they take a feeble form,
when they can be easily contained.
If not they rise to dominance.
When in domination, only one takes over.
For example in the most evolved stage
when Rāga is dominant, other Kleśa
such as Dveṣa are not apparent.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 4

“Illusion is the field out
of which the others grow,
though they may appear
as if asleep, or arise weakly,
be inconsistent or dominant.”
– Paul Harvey on Yoga Sūtra Chapter Two verse 4

“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

“Pratyāhāra is not feeding the tendency of the Citta
to automatically form a positive, negative, or neutral
identification with whatever stimuli the senses present to it.
From that, we can begin to understand how their external gathering
activities stimulate our conscious and especially, unconscious choices.
From this, we can begin to understand how the impact
of this sensory knowing can lead us to travel in different directions
and trigger different levels of response, often without us being really
conscious of how deeply their input stimulates our psychic activities.
From these responses, there will be the inevitable re-actions,
again quite possibly unconscious and multilevelled,
according to our psychic history in terms of our memory,
habit patternings and deeper memory processes.
From those initial insight, we can begin to understand
and interact in how we can resist unconsciously slipping
into the trance states that can so often culminate with
the  Kleśa manifesting fully in the entrancing dance of
Udārā Rāga, or Udārā Dveṣa, or Udārā Abhiniveśa,
the potent and profligate children of Avidyā.”
– Paul Harvey on Yoga Sūtra Chapter Two verse 54
