In hinduism, Vishnu is a God who act as a preserver. He is like a gardener, a leader who is active unlike Shiv, who is the passive one. Vishnu lives in Vaikunth, the heaven which is ocean of milk. Vishnu rest on a serpent called as Shesh Naag, with Lakshmi sitting besides him. In this state he is called Narayan (maybe derived from ‘neend’ which means sleep).
Vishnu only open his eyes when devas pray to him and ask for protection. Devas are sons of Aditi and god of elements ( fire, water, wind etc). They are often threatened by Asura, who are their half brother, sons of Ditti.
When Vishnu wakes up from his sleep, a lotus blooms from his navel and another god Brahma emerges.This relationship is a symbolic mutualism. One can say that Brahma is born out of Vishnu’s conscious thoughts when he opens his eyes. Or Vishnu is, like a fetus connected to the creator Brahma via lotus which is symbolic of placenta.
Brhama is the seeking god, who seeks for answers. Brahma did not make the mortals, he simply made them aware of the world. And he, himself is mark of Vishnu’s consciousness.
Another major god is hindu mythology is Shiva. He is worshiped as destroyer of the universe. He is a hermit who lives on snow cladded mountains, where nothing grows and no animal lives. He sits on a tiger skin and meditates. He doesn’t care about the world and does not wish to interact. He is the maha yogi, who has destroyed Kama, the god of love. He is married to Shakti.
When Shiv has his eyes shut, the nature becomes wild and untamed. It becomes blood thirsty and Shakti takes form of kaali. When Shiva’s eyes are open, he is called as ‘Shankar’ the benevolent one. And Shakti takes form of Gauri, innocent and giving like a cow (cow in Hindi means Gaaye from which the word Gauri is derived).
Nature is called as ‘Prakriti’ in Sanskrit. And Shakti is symbolic of nature. When the god’s eyes are closed, when his mind is not aware of the goddess, the prakriti is unorganized. But as soon as the god opens his eyes, he looks at the goddess (Darashan), Prakriti is organized and giving. Humans should understand that just by Darshan, we can make changes to our lives. Therefore in Hindu temples, people mostly go just to look at the god.
