The word yoga is derived from the Sanskrit root yuj, which means to join.
The science of Kriya yoga teaches the method of merging the individual will with the cosmic will by controlling the mind and it’s modifications, thereby attaining liberation. On the physical plane, yoga bestows good health and physical efficiency; on the mental plane concentration, balance of mind and peace.
On the spiritual plane, it guarantees liberation from the chain of birth and death and offers eternal bliss, immortality, perfection and everlasting peace. The ultimate objective of yoga is not only individual liberation but the transformation of the entire human race.
It aims to instill a divine nature and life into the physical, mental and spiritual life of humanity. Yoga has several branches but Kriya Yoga is the essence of all yogas.
