The Bhavacakra (Sanskrit, भवचक्र) or Wheel of becoming (Tibetan srid.pa'i 'khor.lo) is a complex symbolic representation of saṃsāra in the form of a circle (mandala), used primarily in Tibetan Buddhism. Saṃsāra is the continuous cycle of birth, life, and death from which one liberates oneself through enlightenment.
