Definition
Saṃsāra is the cycle of birth, death, and rebirth — the endless wheel of existence that all beings traverse. It is driven by karma (actions) and vasana (desires): unfulfilled desires at death cause the soul to take a new body, and new actions create new karma, perpetuating the cycle. Saṃsāra encompasses all realms of existence — from the lowest hells to the highest heavens, from insects to gods. No position within saṃsāra is permanent — even the gods eventually die and are reborn. The goal of all Hindu spiritual practice is moksha — liberation from saṃsāra. The Bhagavata Purana describes saṃsāra as a banyan tree with roots above and branches below — the upside-down tree of illusion that must be cut with the axe of detachment.
Etymology
From the prefix sam (सम्), "together, completely," and the root sṛ (सृ), "to flow, wander, pass." Saṃsāra means "wandering through, flowing along" — the continuous passage of the soul through successive bodies.

Bhagavad Gita 15.1Interpretations Across Traditions
Advaita Vedanta
Saṃsāra is ultimately illusory — it is caused by ignorance (avidya) and sustained by desire. Upon jnana, saṃsāra is recognized to have never truly existed. "There is no bondage, no liberation."
Bhakti traditions
Saṃsāra is the ocean of suffering (bhava-sagara) that can only be crossed by devotion to God. God's grace lifts the devotee out of the cycle.
Buddhism
Saṃsāra is beginningless and characterized by dukkha (suffering). Liberation (nirvana) is the cessation of craving and the end of the cycle. Saṃsāra and nirvana are not two different places but two different states of seeing.
