Acharya Prashant explains that the doubtlessness of Kabir Saheb arises from the sheer intensity of his suffering and separation from the Divine. He clarifies that love involves the simultaneous realization of separation and the understanding that such separation is false and must end. While common people tolerate minor irritants and psychological discomforts without seeking drastic change, the saint experiences the agony of separation from God as a massive, unbearable issue that cannot be ignored. This intensity makes the resolution of suffering mandatory and inevitable, leading to a state of certainty regarding the ultimate union.
