Introduction
1. Satya Yuga – Matsya (Fish Avatar)
• Satya Yuga is the age of truth and righteousness.
• Lord Vishnu incarnates as Matsya, a great fish, to save humanity and sacred knowledge from a catastrophic flood.
• He rescues the Sapta Rishis (Seven Sages) and the Vedas by guiding King Manu’s boat through the deluge.
2. Treta Yuga – Treta Yuga Avatars (Vamana, Parashurama, Rama)
• Treta Yuga is marked by a decline in dharma, with power-hungry rulers and increasing conflicts.
• Vamana (Dwarf Brahmin) subdues the demon king Bali by reclaiming the three worlds with three giant strides.
• Parashurama (Warrior with an axe) destroys corrupt Kshatriya rulers to restore order.
• Rama, the ideal king, upholds truth and justice, famously defeating Ravana in the Ramayana.
3. Dwapara Yuga – Krishna
• In Dwapara Yuga, dharma declines further, and deceit, greed, and wars become common.
• Krishna, the eighth avatar of Vishnu, plays a key role in the Mahabharata, guiding Arjuna in the Bhagavad Gita and ensuring the destruction of adharma (unrighteousness).
• He also defeats tyrants like Kamsa and Shishupala, and establishes righteousness through his divine leelas (pastimes).
4. Kali Yuga – Kalki (Yet to Appear)
• Kali Yuga is the age of darkness, where dharma is at its lowest, and corruption, dishonesty, and materialism dominate.
• Kalki, the final avatar, is prophesied to arrive on a white horse, wielding a sword of fire, to cleanse the world and restart the cycle with a new Satya Yuga.
These Yuga Avatars show how Vishnu manifests in different ways to maintain balance in the cosmos.
