"I know not how, but it is..."

The phrase "I know not how, but it is..." expresses a sense of belief or certainty about something occurring or existing, despite lacking understanding of the mechanism or reasons behind it. It reflects trust or acknowledgment that a certain outcome or truth is real, even if the speaker cannot explain how or why it happened. This sentiment often appears in contexts where intuition, faith, or experience confirms a fact beyond empirical explanation. Essentially, it conveys a recognition of an undeniable reality, despite the absence of scientific or rational understanding.
