Mantra Yoga
Mantra Yoga is actually a form of meditation. People who practice mantra yoga have to chant a certain mantra until they transcend their mind and discover their consciousness. Mantra yoga has been proven to have unique healing potentials. There are three ways of chanting the mantra: ‘baikhari’ (chanting the mantra loudly to remove unwanted thoughts),’upanshu’ (chanting the mantra in low voice which can only be heard by the chanter), and ‘manasik’ (this involves the repetition of the mantra in the chanter’s mind).
Raja Yoga
Raja Yoga “royal yoga”, “royal union”, also known as Classical Yoga, is concerned principally with the cultivation of the mind using meditation (dhyana) to further one’s acquaintance with reality and finally achieve liberation. Raja Yoga is sometimes referred to as Astanga (eight-limbed) yoga because there are eight aspects to the path to which one must attend. Patanjali himself called his system of yoga ‘Kriya Yoga’.
