confirmation within oneself of the sense taught by the teacher, by means
of arguments showing it alone to be suitable. 'Meditation'
(nididhyasanam) finally means the constant holding of thai sense before
one's mind, so as to dispel thereby the antagonistic beginningless
imagination of plurality. In the case of him who through 'hearing,'
'reflection,' and meditation,' has dis-dispelled the entire imagination
of plurality, the knowledge of the sense of Vedanta-texts puts an end to
Nescience; and what we therefore require is a statement of the
indispensable prerequisites of such 'hearing,' 'reflection,' and so on.
Now of such prerequisites there are four, viz. discrimination of what is
permanent and what is non-permanent; the full possession of calmness of
mind, self-restraint and similar means; the renunciation of all
enjoyment of fruits here below as well as in the next world; and the
desire of final release.

Without these the desire of knowledge cannot arise; and they are
therefore known, from the very nature of the matter, to be necessary
prerequisites. To sum up: The root of bondage is the unreal view of
plurality which itself has its root in Nescience that conceals the true
being of Brahman. Bondage itself thus is unreal, and is on that account
cut short, together with its root, by mere knowledge. Such knowledge is
originated by texts such as 'That art thou'; and work is of no help
either towards its nature, or its origination, or its fruit (i.e.
release). It is on the other hand helpful towards the desire of
knowledge, which arises owing to an increase of the element of goodness
(sattva) in the soul, due to the destruction of the elements of passion
(rajas) and darkness (tamas) which are the root of all moral evil. This
use is referred to in the text quoted above, 'Brahmanas wish to know him,'
&c. As, therefore, the knowledge of works is of no use towards the
knowledge of Brahman, we must acknowledge as the prerequisite of the
