There are four yugas widely accepted in Hinduism. They are :
1. Satya yug
2. Treta yug (Ramayana)
3. Dwapara yug(Mahabharata)
4. Kal yug(Present)
In Satya yug, the fight was between two worlds (Devalok & Asuralok). Asuralok being the evil, was a different WORLD.
कदाचित् कालिन्दी तट विपिन सङ्गीत तरलो
मुदाभीरी नारी वदन कमला स्वाद मधुपः
रमा शम्भु ब्रह्मामरपति गणेशार्चित पदो
जगन्नाथः स्वामी नयन पथ गामी भवतु मे ॥१॥
Sometimes in great happiness Lord Jagannatha, with His flute, makes a loud concert in the groves on the banks of the Yamuna. He is like a bumblebee who tastes the beautiful lotus-like faces of the cowherd damsels of Vraja, and His lotus feet are worshiped by great personalities such as Lakshmi, Siva, Brahma, Indra and Ganesa. May that Jagannatha #ଜୟଜଗନ୍ନାଥ#JaiJagannath#JagannathPuri#HappyRathYatra
