"Any emotion, if it is sincere, is involuntary"

This quote by Mark Twain recommends that any feeling we feel is real and can not be faked. It implies that emotions are not something we can manage or manipulate, but rather something that is natural and instinctive. It suggests that we can not choose how we feel, which our emotions are a reflection of our real selves. This quote encourages us to be truthful with ourselves and to accept our feelings, even if they are tough to handle. It also suggests that we ought to not repent of our emotions, as they belong of who we are. Ultimately, this quote motivates us to embrace our emotions and to be real to ourselves.
