Vishnu is often depicted as resting on Shesha. Shesha is also considered a servant as well as a manifestation of Vishnu. He is said to have descended to Earth in two human forms or avatars: Lakshmana, brother of Rama; Balarama, brother of Krishna. "Shesha" in Sanskrit texts, especially those relating to mathematical calculation, also implies the "remainder" – that which remains when all else ceases to exist." I have written a number of articles on the concept of Time in Hinduism which is different from that of the west. While the Western Science designates Time as Linear, Hinduism calls it Circular and Non Linear(Please read my post Time Non Linear, Cyclic) Now Quantum theory has proved that Time is not linear.
