Feeling joyful is not necessary for presence, but it's one of the most powerful ways to induce it. Joy creates an almost instantaneous sense of expansion — an inner smile that's like a warm bath. Some call this warm bath "flow" or "spirit." Experiencing it connects us to ourselves and to everyone and everything around us.
Think about someone or something that you love. This could be a child, a place in nature, or a favorite memory. Whatever you choose, make sure that just reflecting upon it creates an automatic inner smile. Then surrender to that inner smile. Let it light you up. Feel it spread though your body and even beyond it, uniting you joyously with your surroundings.— Raphael Cushnir in How Now
