"one attains freedom from the Wheel of Things"

The Wheel of Things refers to the Bhavacakra or Wheel of Becoming. The Bhavacakra represents the Buddhist concept of Saṃsāra: the cycle of birth (jāti), followed by decay and death (jarāmaraṇa). Buddhists believe that all beings in the universe are enslaved by the Wheel of Becoming, which can only be escaped through enlightenment.
