2.55 Prajahati etc.  [The expression  'a man-of-stabilized-intellect' denotes] a  man whose intellect has stabilized, i.e., has grown roots.  Growing roots is growing roots permanently  on the Self.  For, if that is achieved, the agitation in the form of desire born of the distraction by sense-objects comes to an end.  Therefore, the nomenclature  'a man-of-stabilized-intellect' applied to a man-of-Yoga, has an etymological sense and it is appropriate in this way.  In this manner one estion has been answered.
