The only way to prove cause and effect in this world is through your own actions: how much you give determines how much you will receive.
A disciple asked a Zen master, "Master, how can I control my emotions and not get angry when things go wrong?" The Zen master replied, "If you believe deeply in karma, you will not be deluded; all grievances are caused by karma, and without delusion, there is no anger." Getting angry is like drinking poison and expecting others to suffer. Leave space in your heart and do not let resentment fill it. To punish yourself with others' mistakes is foolish; to inspire yourself through others' achievements is wise.
Buddha is not an idol, but the fruit of life's spiritual practice. One does not need to burn incense or bow; the Buddha resides in the heart, not outside the body. The Buddha is a predecessor, and humans are future Buddhas. The Buddha is Buddha because he saw through the patterns others could not and achieved what others could not. Humans are human because they are entangled in seven emotions and six desires, unable to see through or break out. If one can achieve sudden enlightenment and learn contentment, we can all become Buddhas.
One who remains calm amidst events can handle great matters; one who is neither angry nor resentful when slandered can navigate chaos; one who does not avoid or fear difficulties can shoulder heavy responsibilities; one who is neither jealous nor greedy can execute great strategies; and one who is neither impulsive nor restless can establish a firm foundation. Youth is hope; as long as we strive, hope lies ahead. Just as flowers bloom only through effort, the brilliance of ideals shines through hard work.
