Kriya Yoga is a scientific technique that closely follows the method of Patanjali. By the practice of Kriya Yoga one attains a new goal of happiness, awakening and self-realization that enables one to live according to the highest existence. One will feel the presence of God and perceive Him in every object, every thought and feeling. By achieving his own Self-realization one will understand that Kriya Yoga is the best and offers the most scientific and easy technique of liberation.
In his yoga aphorisms, sage Patanjali says –"Tapah, svadhyaya, Iswarapranidhanani Kriya Yoga", i.e. "Mortification, study and surrendering the self to God are called Kriya Yoga." In other words working towards yoga, i.e. union, which is achieved in Samadhi, is called Kriya Yoga and consists of all the preliminaries. Control of the body is called the physical tapas, but the real tapa is inhalation by which the mental wave is controlled. Repetition of scripture is called svadhyaya, but its real meaning is self-study that leads to Self – realization. Worship of God means to perceive Him everywhere, within and without.
