Life does not merely let us experience and learn; it allows us to deeply understand. A clear mind makes everything bright, while a turbid mind makes everything dark; a deluded mind leads to confusion, while an awakened mind finds Zen in all things. The heart is the director of life's drama, and thoughts are the negatives of life's scenes. All roots lie within the heart. Obsession and attachment, resentment and hatred, only cause the heart to churn and the person to be uneasy. Only by letting go can one be light and natural. Wisdom and foolishness are separated by a moment's thought; heaven and hell lie between one thought. Releasing troubles turns them into bodhi; a shift in mood turns the sky clear.
There are always people who cannot let go of memories from the flow of time. If you truly cannot let go, remember this: besides tears, time is the only thing that can wash away all pain. Time is the elixir for healing emotional wounds. There are no paths in the world that cannot be walked, only people who cannot figure it out. Cheer up! Find something to do casually. As time goes on, the pain will fade, like tea that is constantly diluted. Eventually, the bitterness will be gone, leaving only a hint of sweetness.
There are always people who master a math problem while you are cutting fruit, people who remember a word while adjusting the angle in Angry Birds, people who read a chapter of a textbook while you play a round of Dota, people who complete a reading comprehension set while you play a match of NBA 2K, people who listen to an Audio Section A while chatting with others, people who reflect on their day's gains and losses while you are fast asleep, and people who run faster than you. Will you continue to waste your time?
