Unlike other 'styles' of yoga, Rajadhiraja Yoga is not a style of yoga as such but rather a school of yoga. Broadly speaking it is classical yoga encompassing a variety of practices.
What in today's world is understood as a style of yoga mainly pertains to the style or way in which asanas are performed or executed.
Classical yoga however, the way yoga was traditionally practiced, is far more comprehensive and not limited to asanas alone. Classical or Raja Dhiraja yoga is a complete system of self-transformation, including a wide variety of practices, designed to develop body, mind and soul.
Raja Dhiraja Yoga, or in other words, 'the yoga of the king of kings' is a more extensive and comprehensive form of Ashtanga Yoga. This term was first coined by Ashtavakra, author of the famous philosophical text Ashtavakra Samhita over 2000 years ago
The present day form of Raja Dhiraja Yoga uses the eight-limbed structure as its basis, but includes techniques of the original system, given by Shiva, which were lost or overlooked -- clarifying and correcting misinterpretations -- and with recent additions brings the whole practice into relevancy for modern day life and human psychology.
In terms of asana practice (which is just one of the limbs, the 3rd limb, of Patanjali's Ashtanga yoga), a specialty of the Raja Dhiraja school is that there is great emphasis on proper breathing and certain aspects of pranayama are incorporated in the asana practice as well.
This is important, because pranic energies are to be awakened and moved throughout the body during asana practice in order to facilitate deep healing and to direct prana, or vital energy, to various inner organs and glands.
When this is accomplished, asana practice results in a general sense of well-being, which can be felt on the physical, mental and emotional level. Hence, the emphasis is on proper breathing, proper positioning and a quiet but persistent flow of movement.
