Bondage in Buddhism: Temporal or Beginningless?

In Buddhist philosophy, particularly within various schools like Theravāda, Mahāyāna, and Yogācāra, the concept of saṃsāra (cyclic existence) is central characterized by suffering, ignorance, and rebirth. A key metaphysical question arises: How did bondage—the state of being trapped in cyclic existence begin? Was there a specific point in the past time or cause that marked the start of sentient beings' entrapment? Or conversely, is bondage considered beginningless, similar to the doctrine held by certain Vedānta schools which maintain that ignorance (avidyā) has no beginning but can have an end?
