The cycle of samsara is a core concept in Buddhism, describing the endless cycle of birth, death, and rebirth. This perpetual loop is driven by karma and the Three Poisons: ignorance, attachment, and aversion. Understanding samsara is crucial to grasping the Buddhist path to liberation.

Buddhism offers a way out of this cycle through the Eightfold Path, which aims to eliminate the Three Poisons. By following this path, practitioners can break free from samsara and achieve nirvana - a state of perfect peace and freedom from suffering. This journey is at the heart of Buddhist practice.

The Cycle of Samsara

Samsara and rebirth cycle

• Continuous cycle of birth, death, and rebirth in the realm of existence driven by karma and conditioned by the Three Poisons (ignorance, attachment, aversion)
• Beings reborn into various realms based on past actions (karma) including human, animal, hungry ghost, hell, asura, and heavenly realms
• Cycle continues until attainment of liberation (nirvana) through practice of Buddhist path (Eightfold Path)

Causes of samsara perpetuation

• Root causes are Three Poisons: ignorance (fundamental misunderstanding of reality), attachment (clinging to pleasant experiences), aversion (rejection of unpleasant experiences)
• Law of karma governs rebirth cycle with positive actions leading to higher realms and negative actions leading to lower realms
• Twelve Links of Dependent Origination explain causal chain perpetuating samsara, each link conditioned by previous one forming continuous cycle (birth, aging, death)

Karma creation factors

• Ignorance root cause of samsara leading to misunderstanding of reality giving rise to attachment and aversion
• Attachment creates positive karma through actions to obtain and maintain pleasant experiences (generosity, kindness)
• Aversion creates negative karma through actions to avoid or eliminate unpleasant experiences (anger, violence)
• Accumulation of positive and negative karma determines nature of rebirth in samsara cycle (human, animal, deity)

The Path to Liberation
