“It should not be inferred that all of
these faculties of the mind, such as
observations, inference, memory, imagination,
inactivity, hyperactivity, are detrimental.
They are necessary to life, but left to itself
the mind develops its own way of movement and we
end up unable to take full advantage of these faculties.
That is why the Yoga Sūtra says that all activities
of the mind could be favourable or unfavourable.”
