This is based on a famous quote from the First Tsoknyi Rinpoche, who lived in the 19th century. It points to the basic truth that the ordinary conditioned mind is like clothing that covers a beautiful, inherently aware and limitless being that is our real face. We are all made of the same heart-mind as The Buddha. We just forgot. Our spiritual journey and the practices that we learn on the way are about uncovering and appreciating what is already there, as much as developing capacities and powers for that purpose. Our wise heart already knows this, let it call us!
