Similar Schools
There are other schools of Yoga that teach Sahaja Dhyan, all of which require shaktipat diksha. I have found these schools, several of which I have been associated with in the past, to be similar enough that I consider their teachings complimentary to Sahaja Siddha Yoga. This is not necessarily an endorsement of any particular teacher belonging to one of these lineages, but I do believe the lineage teachings of each school to be valuable. Because some schools are known by the same name, I have included the names of their most prominent or founding guru for those sects.
