The prior limb
Pratyahara involves withdrawing the senses from external phenomena.
Dhāraṇā builds further upon this by refining it further to
ekagrata or
ekagra chitta, that is continuous, uninterrupted lucid awareness. The commentarial tradition interprets it as single-pointed concentration and focus, which is in this context cognate with
Samatha. Gregor Maehle defines Dharana as: "The mind thinks about one object and avoids other thoughts; awareness of the object is still interrupted." The difference between
Dhāraṇā,
Dhyāna, and
Samādhi, which together are called
Samyama, is a gradual one of intensity and uninterruptedness. ==See also==
