Why does the speaker state that death is not mighty and dreadful?

The speaker suggests that death is not mighty and dreadful because it is a natural part of life, rather than an end to existence. By viewing death as a transition rather than a termination, it loses its power to instill fear. The speaker emphasizes that death should not be seen as a formidable force, but rather as an inevitable aspect of the human experience, which can bring peace rather than dread. In this perspective, death becomes something to accept, rather than something to fear.
