Studies of "genuine" happiness suggest that a continuous process of bare attention to one's physical sensations without reaction, breathing (in breathing and outbreathing), feelings, mental states (anger, affective feelings), & loving-kindness feelings towards oneself and others lead to a state of happiness and serenity \cite{milton2011mindful,wallace2014mind}. Limited empirical studies suggest that facial expression of novice and experienced meditators change as a result of insight meditation \cite{choi2012happy,NEZLEK20161,campos2016meditation}. Hence, insight meditation practice can be a valid setting to study and validate happiness measures as opposed to community based surveys of random individuals \cite{salzberg2010real}. However, no research as yet has validated the facial expressions with subjective questionnaires to validate the association of happiness with facial expressions. Advances in computation and available tools allow for automated facial expression analysis through machine learning \cite{perveen2016facial,koutlas2009image}
