The understanding of it [absolute] is very important as a beginning point. Then you can use meditation, further reasoning, long-term familiarity etc., you can use all kinds of methods to deepen this understanding and to have it counter the instinctual sense of being an absolute you.
So that's the process of understanding, and through that process, if you have a deep realization of the selflessness in regard to your absolute self, then it releases your relational self to be happily interconnected with everything in a blissful way. Then you yourself have "no problem" in the sense of no suffering. You reach Nirvana.
