Acharya Prashant explains that the only essential thing in life is truth. He clarifies that companionship and love are not essential in themselves; they are only valuable if they serve as a medium toward the truth. If a companion or a particular kind of love becomes a hurdle to truth, it is toxic and should be discarded. He emphasizes that the essence of life is the self or truth, and anything that does not lead to liberation from inner suffering and ignorance is a distraction. When choosing a partner, one must look for someone who elevates them and helps them overcome their inner haze, rather than focusing on superficial attributes or romanticized notions.
