The Rig Veda, the oldest existent text, is composed primarily of the cognitions of a small group of rishis or seers. 10 families of rishis account for 95% of the verses in the 10 mandalas or books.
There are 7 key rishis known as the Saptarishi, said to incarnate after the universe is reborn to restore the cognitions in consciousness and thus awaken that knowledge in the collective. They are Brahmarishi – knowers of Brahman. Ancient India named the 7 stars of the Big Dipper constellation after them.
However, some understanding about them seems lost. For example, I’ve noticed that after their human birth and the cognitions, they live outside our universe in the Chittamaya kosha, managing the affairs of our universe in consciousness.
The roles of the Saptarishi are alternated. While the rishis sit together, other beings apprentice for a role through a series of lifetimes. When their training is complete, they replace a rishi who then has some choice in a new role. This may be one reason the names of the rishis vary in various texts.
There are a series of correlations that suggest a relationship between the Saptarishi and the chakras. Perhaps that level and kosha is their specialty. This part is speculative but the correlations appear high.
There is 7 primary chakras, 7 Saptarishi, and 7 koshas. Most of the 7 rishis are the primary cognizers of the “family” Mandalas of the Rig Vedas: 2-8. Those mandalas correspond to the Prakriti and elements that have a correspondence with the chakras and koshas.
For example, Vishvamitra of the Bharata family is the primary cognizer of the 3rd Mandala, including the Gayatri mantra. The third mandala is associated with the water element, the prana kosha (our energy/ emotional body), and the sex chakra.
Here are the correspondences in table form. The alignment isn’t perfect but is surprisingly aligned, suggesting some detail is off here. Curiously both discrepancies are at the 2 ends.
|3||2 Sex||-Vishvamitra (Bharata)||Water||energy, prana||Energy/ Emotional|
|4||3 Gut||-Gautama (Angiras)||Fire||field||Mental/ senses|
|5||4 Heart||-Atri||Air||geometry||Intellect/ Intuition|
|6||5 Throat||– Bharadvaja (Angiras)||Space||vibration||Bliss/Causal|
|7||6 Head||-Vasishta (Ishvaku)||C. Mind||Chitta/ flow||Creation/ Gap|
|8||7 Crown||Kanva (Angiras)||C. Intellect||–||\/|
|9||– [soma]||-Kashyapa*||Cosmic Ego||Atman||Consciousness|
“-” indicates a Saptarishi
*For the root chakra, the sage of the second mandala is Gritsamada yet the Saptarishi is likely Jamadagni (Angiras/Bhrigu). For the crown, Kanva is not one of the 7. Kashyapa is but is associated with the 9th soma mandala. Soma enters us through a gland between the crown and forehead chakras. It wouldn’t surprise me if the crown manages that.
The picture isn’t completely clear but there is some potential insight into the Vedas here.
