Tibetan Buddhist Cosmology: Six Realms, Bardos & the Wheel of Life
Share
BY NICOLE LAU
Introduction to Tibetan Buddhist Cosmology
Tibetan Buddhist cosmology presents a complete map of existence—from the hell realms to the god realms, from death through the bardo states to rebirth. At its heart is the Wheel of Life (Bhavachakra), a profound teaching diagram showing the Six Realms of cyclic existence (samsara), the Three Poisons that bind us, and the path to liberation. This is not mere mythology but a psychological and spiritual map: the realms represent both literal destinations after death and states of mind experienced in life, the bardos reveal the journey between incarnations, and the entire wheel teaches that suffering arises from ignorance and can be transcended through awakening. Understanding this cosmology provides the foundation for Tibetan Buddhist practice and the path to enlightenment.
This comprehensive guide explores the Six Realms, the Bardo states, the Wheel of Life, and the cosmological structure of Tibetan Buddhism.
The Wheel of Life (Bhavachakra)
The Complete Teaching
The Wheel of Life is a visual representation of Buddhist cosmology, traditionally painted at temple entrances. It contains:
- The Hub: Three animals representing the Three Poisons
- The Second Ring: Karma—beings rising and falling
- The Six Realms: The outer sections showing six types of existence
- The Rim: The Twelve Links of Dependent Origination
- Yama: The Lord of Death holding the entire wheel
- The Buddha: Outside the wheel, pointing to liberation
The Three Poisons (Hub)
At the center, three animals chase each other:
- Pig: Ignorance (moha) - delusion, not seeing reality
- Snake: Hatred (dvesha) - aversion, anger, aggression
- Rooster: Greed (raga) - attachment, desire, craving
These three poisons are the root causes of suffering and rebirth in samsara.

The Path to Liberation
Escaping the Wheel
The Buddha stands outside the wheel, pointing to the moon (enlightenment):
- Liberation is possible
- The wheel is not ultimate reality
- Through practice, one can escape samsara
- Nirvana is beyond all six realms
The Three Trainings
- Sila (Ethics): Moral conduct
- Samadhi (Meditation): Mental discipline
- Prajna (Wisdom): Insight into reality
Recognizing the Bardos
- Practice recognizing dream state (lucid dreaming)
- Meditate on impermanence and death
- Study the Bardo teachings
- Prepare for death consciously
- Recognize all experience as mind's projection
Practical Application
Recognizing the Realms in Daily Life
- Notice when you're in 'god realm' (pride, complacency)
- Recognize 'asura realm' (jealousy, competition)
- Appreciate 'human realm' (the precious opportunity)
- Avoid 'animal realm' (ignorance, autopilot)
- Notice 'hungry ghost realm' (addiction, craving)
- Recognize 'hell realm' (rage, despair)
Using the Wheel as Mirror
- Which realm are you in right now?
- What poison is active?
- Can you recognize it as mind's projection?
- Can you choose liberation?
