The future Manus or fathers of humanity, and future appearances of Krishna, God, the Supreme Person, in the guise of Visnu or Avatars.
Manu means: father of humanity, ancestor of humanity, man or human being. He is the first human being and is comparable to Adam.
Manu is, in truth, a manifestation of the Lord.
In reality, humanity originates from Manu. From this name derives the Sanskrit word “manusah”, which means “human being” or “coming from Manu”.
Manu himself descends from Brahma, the first being created.
The function of the Manu, or father of humanity, is to populate the entire galaxy and to establish the laws necessary for the harmonious functioning of a just and balanced society. He also belongs to the group of the twelve great authorities in matters of spirituality. They are all great saints, great wise scholars, fathers of religion.
The current era is that of Vaivasvata Manu. According to astronomical calculations, we are now in the twenty-eighth cycle, that of Vaivasvata Manu.
In one day of Brahma, the demiurge, the first created being and ruler of our galaxy, succeed fourteen fathers of humanity, which each live for a period spanning seventy-one cycles. Each of these cycles consists of four ages: the Golden Age, the Silver Age, the Copper Age and the Iron Age.
We are currently in the period of Vaivasvata's reign Manu. We are currently going through the twenty-eighth cycle, the one that corresponds to the reign of Vaivasvata, the present father of humanity.
Each Manu or father of mankind lives seventy-one periods of four ages, and fourteen of these fathers of mankind follow one another during a day of Brahma, the demiurge and regent of our galaxy placed in this position by Krishna, God, the Supreme Person. Each galaxy is governed by a Brahma. A Brahma day corresponds to a thousand cycles of four ages, and as many its night. A cycle consists of the Golden Age, Silver Age, Copper Age, and Iron Age. Also, these four ages repeated a thousand times form one day in the life of Brahma, the celestial being second creator, and each of his nights lasts as long. A Brahma day lasts 4,320,000,000 years, four billion three hundred and twenty million earth years.
