Manu refers to a root race or a group of souls inhabiting a vast time
period (era or epoch) on earth. The concept of Manu is found among
Native American tribes, too. The Hopis describe this term as worlds e.g.
fourth world, fifth world. Manu is also a mythical, cosmic being who
oversees the souls during their incarnation processes throughout the
duration of that specific time period. Some consider Manu a type of
spiritual office, not unlike a “World Teacher.” For example, one
evolved-cosmic being will serve as Manu for one world cycle, and when it
ends, it moves on in the evolutionary process. A different entity
serves as Manu for the next group. Each group of souls has a different
energy and purpose. Seventh Manu children will possess advanced
capabilities—astute intellect, vast spiritual knowledge, and keen
psychic abilities. Forerunners of the Seventh Manu will pave the way for
this metaphysically venerated population. Carrying less Karmic burden
than those of the past, these forbearers of ever-increasing
enlightenment promote a sense of higher consciousness. As Dharma
flourishes, the Seventh Manu, sponsored by the Beloved Mother Mary,
proliferates.
