Temples were places where the worship was done so that the entire society could benefit.
This knowledge of the science of worship is what many Gurus provide via Deeksha.
This is the tradition that is in existence in Bharat since ages.
And there are Sampradayas and Gurus who give Deeksha or knowledge of worship of Divine irrespective of status, caste or gender.
All should find a Guru and follow Sampradayas which suits them.
