The Yoga Suttras of Patanjali begins with the well-known idea: “Yoga is the inhibition [nirodha] of the modifications [vritti] of the mind [citta]." (I.K. Taimni)
This aspect of control of the mind is an important principle of Raja Yoga. Yet Raja Yoga is also the heart of The Bhagavad Gita (the Song of the Lord) and is just as central to the teachings of Theosophy (Brahma Vidya or Divine Knowledge) concerning meditation.
Why is Raja Yoga important? How is consciousness within the Theosophical principles or vehicles affected by Raja Yoga? And what will be the future of meditation?
