<P> Dhyana is integrally related to Dharana, one leads to other . Dharana is a state of mind, Dhyana the process of mind . Dhyana is distinct from Dharana in that the meditator becomes actively engaged with its focus . Patanjali defines contemplation (Dhyana) as the mind process, where the mind is fixed on something, and then there is "a course of uniform modification of knowledge". Adi Shankara, in his commentary on Yoga Sutras, distinguishes Dhyana from Dharana, by explaining Dhyana as the yoga state when there is only the "stream of continuous thought about the object, uninterrupted by other thoughts of different kind for the same object"; Dharana, states Shankara, is focussed on one object, but aware of its many aspects and ideas about the same object . Shankara gives the example of a yogin in a state of dharana on morning sun may be aware of its brilliance, color and orbit; the yogin in dhyana state contemplates on sun's orbit alone for example, without being interrupted by its color, brilliance or other related ideas . </P> <P> Samadhi (Sanskrit: समाधि) literally means "putting together, joining, combining with, union, harmonious whole, trance". </P> <P> Samadhi is oneness with the subject of meditation . There is no distinction, during the eighth limb of yoga, between the actor of meditation, the act of meditation and the subject of meditation . Samadhi is that spiritual state when one's mind is so absorbed in whatever it is contemplating on, that the mind loses the sense of its own identity . The thinker, the thought process and the thought fuse with the subject of thought . There is only oneness, samadhi . </P> <P> Samadhi is of two kinds, with and without support of an object of meditation: </P>
