Acharya Prashant explains that defining love is futile because a definition is merely words and does not provide the actual experience of love. He compares this to explaining the chemical composition of water to a thirsty person, which does not quench their thirst. He describes love as a state of mind where one is complete and does not seek another out of a sense of lack or the expectation of receiving something. Love is the mind's own bliss and is synonymous with truth.
