Acharya Prashant explains that bitter experiences from the past happen precisely so that you can live the present with sweetness. He addresses the questioner's underlying assumption that if there were no bitter experiences in the past, the present would be sweet. The speaker refutes this, stating that this indicates a misunderstanding of some fundamental aspects of life. He clarifies that the way nature has made us, the present is bound to be bitter. The human child is not constructed in a way that it gets a sweet present for free. He elaborates that unless a person gains knowledge from life, scriptures, or a Guru, every moment of their present will be bitter. This is certain because human consciousness is never satisfied with just its physical life. A human is unique in this regard; unlike other animals in nature who are content with their physical existence, a human's consciousness is never satisfied. It constantly seeks something more, which leads to a perpetual state of dissatisfaction, a feeling that something is amiss. This inherent restlessness is the source of bitterness. This is why the present moment for a human is naturally bitter, a concept echoed by Buddha's teaching that life is suffering. Therefore, having bitter experiences in the past is not surprising; it is a consequence of our inherent nature. The path to sweetness is not to avoid bitterness but to learn from it. The bitterness life offers is the very tool to be used for the investigation of sweetness. Sweetness is not free; the price is to use the bitterness to learn. One must not run away from bitterness but enter it, get close to it, and understand every fiber of it. By asking what mistakes were made in living and thinking that led to these bitter experiences, one can learn. As you identify these flaws, the present will fill with sweetness. If you only complain about the past, the present will also remain bitter. The choice is to use bitter experiences as a foundation for learning, which is the only way to attain sweetness in the present.
