Life is already filled with enough worries and troubles; adding an extra mental burden will only leave you exhausted for a lifetime. Only by letting go of the burdens we impose on ourselves can we find true happiness. Only those who know how to let go and avoid self-imposed pressure can discover the secret to a free and easy life. To achieve the ability to "let go" constantly, perhaps we can start by learning to navigate the world with a touch of "muddled" wisdom.
When you truly understand impermanence, you will not be boastful; today's splendor may turn into tomorrow's mess. When you truly understand impermanence, you will not be sorrowful; today's gloom may give way to tomorrow's sunshine. When you understand impermanence, you are neither overly joyful in gain nor deeply wounded in loss, for gain and loss are constantly transforming. When you understand impermanence, everything flows naturally.
There is "heart history" and there is "experience." Heart history guides experience, and experience enriches heart history. If the heart remains young, life remains timeless despite any hardships; if the heart grows old, life feels barren even in times of peace. Life sometimes requires precipitation—having enough time to reflect to become a better version of yourself; life requires accumulation—only by looking back can we sublimate through the tasting of gains, losses, sweetness, and bitterness.
