What term describes feelings or expressions that come from the depths of one's being?

The term that describes feelings or expressions that come from the depths of one's being is "profound." This word conveys a sense of deep significance, intensity, or depth of emotion and thought. When something is described as profound, it typically suggests that it is not only meaningful but also touches upon the core of human experience or understanding.

In the context of feelings or expressions, the use of "profound" indicates that they resonate deeply within an individual, often reflecting strong emotions or insights that are not superficial or trivial. This is particularly relevant when discussing matters of the heart or spirituality, where feelings often run deep and evoke a strong, intrinsic response.

The other options do not convey the same meaning. For example, "presumptuous" relates to overstepping bounds or being overly bold, while "pretentious" refers to claiming a higher importance than is warranted. "Profligate" usually pertains to reckless spending or wastefulness, which does not align with expressing deep feelings. Thus, "profound" stands out as the appropriate term for describing these deep-seated feelings or expressions.
