We practice the Three Dharma Seals to realize liberation.  If you memorize a 5,000 page book on the Three Dharma Seals but do not apply the teachings during your daily life, the book is of no use.  Only by using your intelligence and putting the teachings into practice can they bring you happiness.  Please base your practice on your own life and your own experiences - your successes and your failures.  The Buddha's teachings are jewels, but we have to dig deep in order to touch them fully.
