True art and beauty have no price but the greatest of these is true love. How much can anyone give in exchange for heartfelt devotion and a commitment to consistently seek out the wellbeing of a spouse, child, parent, friend, colleague, relation, neighbour, etc? Material gifts are definitely a great idea; they can be very meaningful, especially in celebratory moments like Valentine, etc but they are not a complete substitute for heart. True love has no price because its worth can never be fully quantified or estimated. What is the value of one heartbeat or the value of a couple of heartbeats, cooperating together and galvanizing the whole being towards another? Priceless.
