महर्षयः सप्त पूर्वे चत्वारो मनवस्तथा।मद्भावा मानसा जाता येषां लोक इमाः प्रजाः ॥

In the beginning I was alone and from Me came the mind and from the mind were produced the seven sages (such as Bhrigu, Vasishtha and others), the ancient four Kumaras (Sanaka, Sanandana, Sanatkumara and Sanatsujata), as well as the four Manus of the past ages known as Savarnis, all of whom directed their thoughts to Me exclusively and were therefore endowed with divine powers and supreme wisdom.The four Kumaras (chaste, ascetic youths) declined to marry and create offspring. They preferred to remain perpetual celibates and to practise BrahmaVichara or profound meditation on Brahman or the Absolute.They were all created by Me, by mind alone. They were all mindborn sons of Brahma. They were not born from the womb like ordinary mortals. Manavah, men, the present inhabitants of this world, are the sons of Manu. The Manus are the mindborn sons of God. These creatures which consist of the moving and the unmoving beings are born of the seven great sages and the four Manus. The great sages were original teaches of BrahmaVidya or the ancient wisdom of the Upanishads. The Manus were the rulers of men. They framed the code or rules of conduct or the laws of Dharma for the guidance and uplift of humanity.The seven great sages represent the seven planes also
