The Cosmic Time and the Creation of the Universe in Hinduism

Hindu philosophy presents a profound understanding of time, creation, and dissolution. These concepts are primarily described in the Puranas and other Hindu scriptures. The cycle of creation and destruction is closely associated with Lord Brahma, Lord Vishnu, and Lord Shiva. In this blog, we will explore these aspects in detail.

How Long is One Day of Brahma in Earth Years?

According to Hindu cosmology, time is cyclical and measured in immense units. One full day of Brahma (which includes both day and night) is equal to 8.64 billion Earth years. This calculation is derived as follows:

• One Kalpa (Brahma's daytime) = 4.32 billion years
• One Pralaya (Brahma's nighttime) = 4.32 billion years
• One full day (day + night) of Brahma = 8.64 billion years
• One year of Brahma (360 days) = 3.1104 trillion years
• The lifespan of Brahma (100 years) = 311.04 trillion years

Brahma is currently 51 years old, meaning the universe has already existed for 155.52 trillion Earth years.

Is the Age of the Universe 155.52 Trillion Years According to Brahma's 51 Years?

Yes, in the context of Hindu cosmology, the current cycle of the universe has been ongoing for approximately 155.52 trillion Earth years. However, this is only within Brahma’s current lifespan. When Brahma’s life ends, the universe undergoes Mahapralaya (great dissolution), and a new cycle begins with the birth of another Brahma.

Modern science estimates that our current universe is around 13.8 billion years old, based on cosmic background radiation and the rate of expansion. This is much shorter than the 8.64 billion-year duration of one Kalpa, and significantly less than the 155.52 trillion years of Brahma's current age. The reason for this apparent gap is that modern science measures only the current phase of the universe, starting from the last known Big Bang.

Hindu cosmology suggests that countless universes have existed before, undergoing cycles of expansion and dissolution, which aligns with the hypothesis of an oscillating universe. While modern science estimates our current universe to be 13.8 billion years old, Hindu cosmology proposes a much larger framework of time, where universes are created and dissolved repeatedly over vast time spans. After 100 years of Brahma, the universe undergoes Mahapralaya (great dissolution), only to be reborn again, much like the theorized cyclical model of the cosmos.

What Happens During Brahma’s Day and Night?

Brahma is responsible for creation during his daytime (Kalpa). The four Yugas (Satya, Treta, Dwapara, and Kali) repeat in cycles during this time. Life, planets, and the universe remain manifest.

At the end of his day, during Pralaya (nighttime), the universe dissolves into an unmanifested state but does not completely disappear. This temporary dissolution means that material elements, souls, and cosmic principles remain dormant until the next Kalpa begins.

During Brahma's night, all living beings, except those in the highest spiritual realms, enter a dormant state. The material universe dissolves into a subtle, unmanifest form, while its fundamental elements remain in a latent state. Although the physical manifestation ceases, time continues to flow, ensuring that when Brahma awakens, the cycle of creation resumes seamlessly.

If the Universe Dissolves During Brahma’s Night, How Can We Say It Is 155.52 Trillion Years Old?

The dissolution during Brahma’s night is only a temporary withdrawal of creation; it is not the Mahapralaya (ultimate destruction). Since Brahma himself is not destroyed, time is still counted from the beginning of his birth. Even though the physical universe dissolves, the fundamental principles of existence remain in Vishnu’s cosmic body, ready to be reshaped when Brahma wakes up.

How Was Brahma Created?

Before Brahma existed, only Maha Vishnu existed in a cosmic ocean called Karanodaka (Causal Ocean). According to the Puranas:

• Vishnu lies on the serpent Ananta Shesha in the Causal Ocean.
• From his navel grows a lotus.
• Brahma emerges from this lotus and begins the process of creation.

How Did Vishnu Come Into Existence?

Vishnu was not created—he is Sanatana (eternal). Hindu scriptures describe Vishnu as the Adi Purusha (Primordial Being). He exists beyond time, space, and creation.

The Vedas and Upanishads describe Vishnu as Nirguna Brahman (formless absolute reality) and also Saguna Brahman (personal deity). He is the supreme source of all existence, and everything emanates from him. Unlike Brahma, who is born within time, Vishnu exists eternally, beyond the material world.

Does Vishnu Create a Multiverse? Does Each Universe Have Its Own Vishnu and Brahma?

According to Hindu cosmology, Vishnu creates not just one universe but countless universes. The Brahma-vaivarta Purana and other scriptures describe that there are infinite universes, each with its own Brahma, Vishnu, and Shiva managing creation, preservation, and destruction.

Each universe has its own Brahma, who emerges from the navel of the Vishnu governing that specific universe. However, beyond all these individual universes is Maha Vishnu (the Supreme Vishnu), from whom all universes originate.

To understand this, imagine an endless ocean with countless bubbles forming and dissolving on its surface. Each bubble represents a separate universe, complete with its own Brahma, Vishnu, and Shiva, governing its cycle of creation, preservation, and destruction. However, all these universes emerge from the same vast ocean—Maha Vishnu—who exists beyond them, sustaining their existence while remaining unaffected by their individual lifespans.

Before the Universe Was Created, How Was Vishnu Living on the Ocean, and Where Did This Ocean Come From?

The Karanodaka (Causal Ocean) is not a material ocean but a metaphysical plane of existence. It is described as existing beyond time and space, emerging from the infinite energy of Vishnu himself. To understand this, imagine a vast cosmic void where creation is yet to begin, but the potential for everything already exists within Vishnu, much like the way a seed contains the blueprint for a massive tree. Vishnu does not need a material habitat; he is beyond physical limitations and exists in a divine state. The Causal Ocean serves as the medium through which the process of creation begins.

Why Did Vishnu Create the Universe, and What Was His Purpose?

Hindu scriptures explain that Vishnu creates the universe as part of an eternal cycle of creation, preservation, and dissolution. Unlike human actions, which are driven by desire or necessity, Vishnu's act of creation is spontaneous and natural. The universe manifests from him, is sustained by him, and ultimately dissolves back into him. This divine process is known as Lila (divine play)—creation is not a compulsion but an expression of his infinite energy and consciousness.

The Bhagavata Purana describes Vishnu as existing in a state of perfect completeness. Creation is not undertaken out of lack or need, but as an expression of divine will. Vishnu remains detached from material existence, even as he manifests the cosmos. Just as an artist paints not out of necessity but as an expression of creativity, the universe emerges from Vishnu as an unfolding of cosmic order.

The universe goes through cycles of birth and destruction, ensuring the eternal nature of creation. The process of creation is not a singular event but a continuous cycle that has no absolute beginning or end. Just as waves rise and fall in the ocean without disturbing its essence, Vishnu manifests and dissolves universes without being affected by their existence.

Does Vishnu Create Souls?

According to Hindu philosophy, souls (Atman) are eternal and uncreated. The Bhagavad Gita (2.20) states that the soul is neither born nor does it ever die; it is indestructible and remains unchanged. Vishnu, as the Supreme Being, does not create souls but governs their journey through the cycles of birth and rebirth. Each soul is bound by karma and takes birth in different forms based on past actions. Vishnu, through his divine will, upholds the cosmic order, providing an environment where souls can evolve spiritually and ultimately attain liberation (Moksha).

Souls were always part of Vishnu, in an unmanifest state. During dissolution, they merge back into Vishnu. When creation happens, they emerge again, based on their past karma.

Conclusion

Hindu cosmology presents a vast, cyclical understanding of time and creation. Vishnu, as the eternal being, creates Brahma, who in turn creates the material world. The universe follows cycles of manifestation and dissolution, but time itself is eternal. The purpose of creation is not mere amusement but an opportunity for souls to evolve and attain liberation.
