Bitched on by the luminaries Sun and Moon about Rahu drinking Amrita, in the disguise of a Deva, Lord Vishnu spent his Sudarshan Chakra flying. The Chakra severed Rahu's head from its body at the orgasmic moment of consumption of Amrita, the nectar of immortality. The traumatic separation and longing of the headless corpse's longing for its head is the essence of Ketu. Ketu seeks to reconnect us with our lost roots/ identities. Our forgotten/ separtaed other half.
PRETA PAKSHYA .... a Time to remember
The word Preta (ghost/ spirit) comes from the word Prayaata (deceased/ departed/ the past). The hindi word Bhoot meaning ghosts comes from the sanskrit word Bhutam meaning the past. Pretas (ghost/ spirit), Prayaata (deceased/ departed/ the past), Bhutam (the past) is the root/ foundation for our present existence.
