Answer

Jainism teaches that the universe is eternal, uncreated, and without beginning or end. It was not created by God. Instead, it exists according to its own natural laws. Jain cosmology explains the structure of the universe, the realms of existence, the movement of time, and the journey of the soul.

Explanation

1) The Jain view of the universe

In Jainism, the universe is called Loka. Everything that exists within the universe is part of Loka. Beyond it is Aloka, which is empty space and has no living beings, matter, or activity.

The universe is often described as having the shape of a standing human figure:

• broad at the top and bottom,
• narrow in the middle.

This symbolic form helps explain the arrangement of the cosmic realms.

2) The two great divisions: Loka and Aloka

Loka

This is the occupied universe. It contains:

• souls,
• matter,
• time,
• space,
• motion,
• rest.

Aloka

This is the non-universe beyond the universe. It contains only empty space. There is no matter, no soul, no karma, and no activity there.

This is important in Jain thought because it shows that existence is bounded and orderly.

3) The three vertical worlds

Jain cosmology divides the Loka into three main regions:

A. Upper World (Urdhva Loka)

This is the region above the middle world. It contains:

• celestial beings,
• heavenly realms,
• higher divine worlds.

These are not eternal abodes of liberation. They are still within samsara, so beings there are still bound by karma.

At the very top of the universe is the Siddhashila or Siddha Loka:

• the realm of liberated souls,
• souls who have completely destroyed karma,
• they live forever in pure knowledge, bliss, and perception.

This is the highest spiritual goal in Jainism.

B. Middle World (Madhya Loka)

This is the world where we live. It contains:

• humans,
• animals,
• plants,
• insects,
• many forms of life,
• continents, oceans, mountains, and rivers.

The most famous part of the middle world is Jambudvipa, the central continent. At its center stands Mount Meru, which is a key cosmic mountain in Jain cosmology.

The middle world is extremely important because:

• only here can souls practice spiritual discipline in the fullest way,
• only human birth gives the best opportunity for liberation,
• the Tirthankars are born here.

---

C. Lower World (Adho Loka)

This is the region below the middle world. It contains:

• hellish realms,
• suffering beings,
• intense karmic consequences.

There are seven hells traditionally described in Jain cosmology. These are not eternal punishments, but places where souls experience the results of very heavy negative karma.

---

4) Jambudvipa and the cosmic geography

Jain texts describe the middle world in great detail.

Jambudvipa

• The central continent of the middle world.
• Divided into regions by mountains and rivers.
• Mount Meru stands at its center.

Other continents and oceans

Jain cosmology speaks of a vast and highly structured arrangement of:

• islands/continents,
• concentric oceans,
• mountain ranges.

This geography is not just physical description. It also shows the orderliness of the universe.

---

5) Mount Meru

Mount Meru is one of the most important symbols in Jain cosmology.

It is:

• the central mountain of the universe’s middle world,
• associated with cosmic order,
• linked with the spiritual and celestial structure of existence.

In Jain tradition, important events connected to Tirthankars are also associated with cosmic symbolism around Meru.

---

6) The realms of living beings

Jainism says that souls can exist in many forms of birth, depending on karma.

These include:

• nāraki beings in hells,
• devas in heavenly realms,
• humans,
• animals and plants,
• and other living forms.

All of these are still within samsara. All are temporary. All are subject to karma and rebirth.

---

7) Time in Jain cosmology

Jainism does not view time as a straight line with a beginning and end. It is cyclical.

There are two half-cycles:

Avasarpini

The descending half-cycle, when moral and spiritual values gradually decline.

Utsarpini

The ascending half-cycle, when values gradually rise.

Each half-cycle has six ages (aras):

1. very good age,
2. good age,
3. mixed age,
4. declining age,
5. very difficult age,
6. worst age.

We are currently believed to be in Avasarpini, the descending cycle.

This explains why spiritual effort becomes harder as time moves forward in the present cycle.

8) The six substances in Jain philosophy

Jain cosmology is closely linked with Jain metaphysics. The universe is made up of six dravyas or fundamental substances:

1. Jiva – soul
2. Pudgala – matter
3. Dharma – medium of motion
4. Adharma – medium of rest
5. Akasha – space
6. Kala – time

These are not “good” and “bad” in a moral sense. They are the basic realities that make cosmic existence possible.

---

9) Karma in Jain cosmology

A central idea in Jainism is that karma is a real subtle material substance that binds to the soul.

Because of karma:

• souls wander through different births,
• experience suffering and pleasure,
• remain trapped in samsara.

Liberation happens when:

• karma is stopped,
• karma is destroyed,
• the soul becomes pure and rises to Siddhashila.

So Jain cosmology is not just about the structure of the universe. It is also about the soul’s journey through that universe.

---

10) The goal of Jain cosmology

The purpose of understanding the cosmos in Jainism is not curiosity alone. It is to realize:

• the universe is vast and disciplined,
• life is governed by karma,
• worldly existence is temporary,
• liberation is possible,
• the highest state is the freedom of the soul.

---

Spiritual Understanding

Jain cosmology teaches a deep spiritual truth:

• Nothing is random.
• Nothing is created by a controlling deity.
• Every soul is responsible for its own destiny.
• The universe functions through eternal natural principles.

This teaching inspires:

• non-attachment,
• humility,
• discipline,
• compassion,
• spiritual effort.

When a Jain understands the cosmos, they also understand their own place in it:

• the world is vast, but temporary,
• karma binds, but can be removed,
• liberation is the highest reality.

---

Takeaway

Jain cosmology presents the universe as:

• eternal,
• self-existing,
• highly structured,
• divided into upper, middle, and lower worlds,
• surrounded by Aloka,
• and governed by karma and time cycles.

Its deepest message is simple: the soul can rise beyond the entire cosmos through right faith, right knowledge, and right conduct.
