They say silence is gold, but maybe calling it pearl also will not really be a bad ideation. Extrovert and introvert exude polarity but the variance of traits outweigh each other beyond belief. Just as a clam which sits in a place beyond centuries enclosed and conserved yet ends up producing a pearl, maybe even us humans meditating and concentrating on ourselves, conserving our thoughts can complete our life cycle. Who knows maybe we might also end up producing our own pearls just like the ‘Enlightened Gautam’.
