How do we explain these Great Beings: Buddha, Moses, Krishna, Christ, Zoroaster, Muhammad, the Bab & Bahaullah? They are somewhat unique and unparalleled in human history and were clearly not ordinary people.
Are they from another world? Did they pre exist? Without a special power how could they have accomplished what they did and who is their equal in influence?
And aren't we in dire need of another Great Spiritual Teacher to revive us spiritually?
I am aware that I am somewhat repeating myself by answering in this thread.
The way I see it comes from my own tantra-yoga tradition and will differ from the Bahai and other religious viewpoints.
It is approximately as follows:
The most important (by far the greatest) personalities of divine status came to this planet in physically ordinary human form at crucial points in history when humanity needed a tremendous push in order to change its course in the right (dharmic) direction.
The descriptions of the first two of these tantric
Maha-kaulas Lord Shiva and
Lord Krishna have been greatly expanded or embelished with religious myth but they once walked the earth looking like ordinary (but very charismatic) human beings as tantric type Guru's who had an enormous impact on the human society of their day (not just in South Asia) by their example and their teachings. They changed the destiny of humanity by their advent.
Lord Shiva lived just before 7000 years ago and Lord Krishna before 3500 years ago both at the time of great stagnancy and upheavals in human society.
A kaula is someone who can raise their kulakundalini at will from the base of the spine up to the seat of God. A Maha-kaula can raise the kulakundalini of any other being with a spinal column at will and meditates on the creatures in His creation.
The third Maha-kaula was
Lord Anandamurti who lived from 1921 to 1990 (roughly the years of fascism and communism), also in South-Asia.
Their teachings are tantric-yogic in nature, not religious but focussing on furthering and adjusting the practice of human Dharma to the needs of the times that continued to change during the course of history.
They are not mere human incarnations but are said to come from the borderline between the Unqualified Consciousness and the Qualified Consciousness and in more or less full control of their own unique destiny.
Of course there have been many other great guru's or teachers called rishi's, prophets, son-of-God, founders of important movements, some more tantric, some less so.
Notable ones were Moses, Lord Buddha, Lord Mahavira, Lord Chaitanya (founder of the bhakti movement), Lord Yeshua, Muhammed, Bahaullah to name just a few of them.
