In the third lecture in the series The Quest for Spiritual Paths, Douglas Gabriel discusses the blood relics of Christ and their provenance over the centuries. He also discusses the two Jesus children.
Ancient Indian lineages carried great wisdom for thousands of years in an unbroken oral tradition back to Manu and the Seven Holy Rishis. Those who were fully clairvoyant in ancient times were able to directly perceive the nature of the interaction between physical matter and spirit.
Every spiritual tradition has reverence for the elders who are called many names: ascended masters, descended avatars, bodhisattvas who become buddhas, the Mother Lodge of the Sun, the Masters of Wisdom, saints, prophets, tulkus, arahats, yogis, yoginis, yidams, great initiates, shamans, kahunas, deities, devas, and hierarchical beings, to name but a few. The distinctions between these vastly different ranks of human and spiritual beings are often confused and deserve clear definition so that discernment can follow.
