The concept of time in Hindu mythology follows a cyclical framework, where creation, preservation, and destruction are repeated endlessly. This cosmic cycle encompasses vast stretches of time, broken into various eras, or yugas, that recur within a grand structure of cosmic time. Central to this structure is the concept of the Maha-Yuga, or Chatur-Yuga (four eras), consisting of the Krita Yuga (also called Satya Yuga), Treta Yuga, Dvapara Yuga, and Kali Yuga, each with distinct characteristics and durations. These yugas vary in length, with Krita Yuga lasting 1,728,000 years, Treta Yuga 1,296,000 years, Dvapara Yuga 864,000 years, and Kali Yuga 432,000 years. Together, these make up one Chatur-Yuga, which repeats over vast epochs.
One day of Lord Brahma, the creator, is equivalent to a thousand Chatur-Yugas, totaling 4.32 billion years, and his night is of equal length. His lifespan, known as a Kalpa, is 100 such Brahma years, amounting to over 311 trillion terrestrial years. Within each Kalpa, there are fourteen Manvantaras, periods each presided over by a different Manu, the progenitor of mankind. Each Manvantara lasts approximately 71 Chatur-Yugas, and during each Manvantara, there are distinct Devas, Indras, and SaptaRishis (seven sages) who guide the universe.
The Manus of Different Manvantaras
- Swayambhuva Manu (1st Manvantara):
Swayambhuva, the first Manu, marked the beginning of time. In this period, Lord Vishnu incarnated as Varaha (the boar) to save the Earth from the depths of the ocean, symbolizing the eternal task of restoration. His consort was Shatarupa. The Devas were led by Yama, and Marichi was the head of the SaptaRishis. This Manvantara lays the foundation for the cosmic cycle of creation, preservation, and destruction. - Svarosisha Manu (2nd Manvantara):
In the second Manvantara, Svarosisha was the Manu, and the Indra of this age was Rochana. Vishnu incarnated as Vibhu, though not counted among the major ten avatars. The Devas included Dushita and others, and the SaptaRishis included prominent sages like Dhattatreya, Atri, and Kashyapa. This era continued the lineage of divine intervention and cosmic order, where Vishnu’s presence maintained the balance. - Uttama Manu (3rd Manvantara):
Uttama Manu presided over the third Manvantara. His sons, Pavana and Srunjaya, were among the Devas, and the SaptaRishis were led by Pramadha. The Indra of this age was Satyajit, and Vishnu appeared as Satyasena, again marking a lesser-known incarnation. The Devas and sages continued to play their roles in guiding the universe, ensuring that divine justice and protection were upheld. - Tamasa Manu (4th Manvantara):
In the fourth Manvantara, Tamasa was the Manu. The Devas were the Satyakars, and the SaptaRishis were led by Jyothis and Vyoga. Trichika was the Indra, and Vishnu incarnated as Hari. While not one of the major avatars, Hari’s presence in this Manvantara maintained cosmic order, ensuring that balance was preserved between the forces of good and evil. - Raivata Manu (5th Manvantara):
The fifth Manvantara saw Raivata as the Manu, Vibhu as the Indra, and the SaptaRishis led by Hiranyaroman and Urthvabahu. Vishnu’s incarnation was Vaikuntan, again demonstrating His continuous role in sustaining the universe. In this period, the divine powers continued their responsibilities, maintaining harmony in the universe. - Chakshusha Manu (6th Manvantara):
Chakshusha was the sixth Manu. The Indra was Indradhyumna, and the SaptaRishis were led by Havishman. Vishnu incarnated as Ajita, who, though not among the major ten avatars, played a crucial role in protecting the universe from chaos. This Manvantara is also significant for the Kurma (tortoise) and Mohini (bewitching woman) avatars, which are traditionally associated with the churning of the ocean (Samudra Manthan), a pivotal event where Vishnu helps secure the nectar of immortality (Amrita) for the Devas. - Vaivasvata Manu (7th and Present Manvantara):
The current Manvantara is ruled by Vaivasvata Manu, son of Vivasvant (the Sun God). The Devas in this age include the Adityas, Ashwini twins, Maruts, and Rbhus, while Purandara (Indra) rules the heavens. The SaptaRishis are among the most well-known: Kashyapa, Atri, Vasishta, Vishwamitra, Gautama, Jamadagni, and Bharadwaja. Lord Vishnu incarnated as Vamana, the dwarf, to restore balance by humbling the mighty King Bali. This age is still ongoing, and we currently live in one of the Kali Yugas of this Manvantara, which began after the conclusion of the battle of Kurukshetra in the Mahabharata.
Future Manvantaras
- Savarni Manu (8th Manvantara):
The eighth Manu will be Savarni, marking the beginning of the next Manvantara, where new Devas, Indra, and SaptaRishis will take charge. This Manvantara will follow the same cyclical pattern of creation, protection, and destruction. - Manus of Future Manvantaras:
Following Savarni, future Manus will include Ruchi (9th), Bhautya (10th), and Merusavarni (11th). The names of the remaining Manus in successive Manvantaras will be Ribhu, Veetdhama, and Vishkvasena. Each of these Manus will oversee the world during their allotted periods, guiding humanity and maintaining cosmic order through the power of Vishnu’s divine incarnations.
The Continuity of Vishnu’s Incarnations
Throughout these Manvantaras, Vishnu’s role as the protector and sustainer of the universe remains central. Although His well-known ten avatars (Dashavatara) are the most frequently cited, several other incarnations are mentioned across different Manvantaras, such as Kapila, Vibhu, Vaikuntan, Ajita, and others. These lesser-known avatars contribute to preserving balance and preventing the spread of evil during their respective epochs, reaffirming Vishnu’s unceasing vigilance and commitment to the welfare of creation.
The Symbolism of Time and Cyclicality
In Hindu mythology, the cyclical nature of time emphasizes the themes of regeneration, transformation, and the constant presence of the divine in the world’s renewal. Every Manvantara brings new challenges, but the eternal presence of the Devas, SaptaRishis, and Vishnu’s avatars ensures that dharma (cosmic order) is preserved. This cycle will continue through countless Kalpas, with the forces of creation, preservation, and destruction perpetually at work.
The story of the Manvantaras provides a framework not only for understanding time but also for seeing the continual involvement of divine power in the cosmic order. In this endless cycle, the gods, sages, and avatars work in tandem to maintain balance, guiding humanity and ensuring that the universe remains a place where good ultimately prevails over evil.
