Siddhayoga
Siddhayoga (Hindi: सिद्ध योग), also known as sahaj yoga, kundalini yoga, shaktipat yoga, maha yoga, shakti yoga, or kriya yoga, is a central element in a guru-disciple relationship. It is understood that the guru transfers shakti (energy) to the disciple through a process called shaktipat. Within this tradition, the process is described as automatically infusing shakti from the guru into the disciple.
Multiple lineages are associated with Siddhayoga, some sharing historical connections and others developing independently. Different groups, even those who are not using the term Siddhayoga, discuss the infusion of kundalini shakti.
Teachings similar to those in Siddhayoga are said to trace back to Tantric masters, such as Abhinavagupta. Within the tradition, Shakti is understood by practitioners as the energy of an eternal soul and is believed to be accessible regardless of religious background. Because of this perspective, Siddhayoga is sometimes viewed as having secular aspects rather than being exclusively Hindu.
