Rebirth is a fundamental concept in Buddhism. But who or what gets reborn? We know human beings do but what about ants, insects or plants and trees? Do all beings undergo rebirth? As the Buddha did not explicitly address such questions in the suttas, it will be mere speculation to try to give a definite answer. However, since rebirth is the result of clinging to the five aggregates, does it mean that the living organisms which are subject to rebirth are the ones complex enough to have and to cling to the five aggregates? This dhamma talk delves into the intricacies of the rebirth concept in Buddhism.
