Acharya Prashant explains that to understand death, one must first understand life. He defines life in the context of 'Prakriti' (Nature/Matter), which encompasses the entire visible, scattered world, both inert and conscious. Within this Prakriti, there is an element called 'aham-vritti', or the I-tendency. He distinguishes between inert objects in nature, like a pen or a glass, which do not proclaim 'I', and beings that do. That which does not say 'I' is 'jad' (inert/insentient). The I-tendency ('aham-vritti') is not a physical thing or a person, but a tendency or modification ('vritti') that constantly seeks to associate with objects ('vastu'). The object it most prefers to associate with is the body ('deh'). The body serves as a vehicle for this I-tendency, which, though not physical itself, is always connected to a physical substance. The purpose of this association is the I-tendency's deep-seated desire for 'mukti' (liberation). This tendency is a form of incompleteness seeking completeness, and the human body is a special creation of Prakriti that provides the potential for this liberation. Life, therefore, is the opportunity for the I-tendency to use the body as an instrument to achieve its ultimate goal of liberation. Prakriti creates beings so that, through them, it can itself be liberated. This is why the I-tendency manifests as a personal ego in countless individuals, as if it is repeatedly trying to find a being who can lead it to liberation. Death is Prakriti's decision. When a body is no longer a useful instrument for this mission, Prakriti ends its existence. This is what death is. The speaker clarifies that it is the I-tendency that is reborn, not the individual ego. He uses the analogy of a lamp's flame: when a lamp is extinguished, its flame does not jump to another lamp; rather, Prakriti lights new lamps. This process is impersonal from Prakriti's perspective, which is ruthless and has no attachment to any single 'lamp' (individual). It creates millions, hoping one will become a 'sun' (achieve liberation). The purpose of life is to reach a state free from suffering, which means a state free from the ego. Committing suicide is a mistake because it means missing the opportunity for liberation that life, and only life, provides. He further explains that spirituality and science are not in conflict. A scientific understanding, particularly of biology, can aid in understanding spiritual concepts. He criticizes the tendency of people to be impressed by gurus who display power and luxury, stating that this is a projection of their own ignorance. An ignorant person will choose a guru based on their own ignorance, being impressed by superficialities rather than true knowledge. The real measure of a healthy body is not its physical fitness for worldly pleasures but its capacity to serve as an instrument for liberation.
