The Pendulum of the Heart: Why Does Excessive Joy Lead to Excessive Sorrow?

Have you ever found yourself so happy you felt like jumping for joy, only to fall into a bottomless sadness just a day later? I once heard a dharma talk by Venerable Thich Chan Quang on the "oscillation of the mind." It offered me a new perspective: emotions that seem opposed, like joy and sorrow, or love and hate, are in fact just two extremes of the same pendulum.

**The Pendulum of Emotion: Great Joy Often Brings Great Sorrow**

Like the pendulum of a clock, if you pull it far to the left and let go, it will swing far to the right. The human mind works in the same way. When you allow yourself to become excessively joyful, you are pulling the pendulum to one side. When released, it will swing to the opposite side with a correspondingly large amplitude.

"If one is excessively happy, beware, for that may be a sign of illness."

When we see someone laughing, joking, and being cheerful every day, we should not be too quick to feel reassured. It may be that they are pulling the pendulum toward joy. When they eventually encounter sorrow, that sorrow will be equally great. A layperson who is new to visiting a temple might be excused, but if a monastic still shows anger and irritability, people will say their practice is poor. Why? Because in the Buddha's teachings (Dharma), an unmoving mind is a supreme requirement.

**Be Cautious with Displays of Excessive Affection**

Do not be too glad when someone cares for your every little need, worrying over every crumb of cake for you. This may be the pendulum swinging toward attachment. When you do something that does not meet their approval, the pendulum will swing toward aversion. There are many such cases in life: the person who is warmly attentive today may not even look at you tomorrow. Therefore, those whose compassion is genuine will love you without showiness, for they harbor no agenda of exploitation. Their love is vast yet does not bind.

"Genuine compassion is a heart that loves all beings boundlessly, without asking for anything in return."

**What is the Root of Stability?**

People are easily swayed between opposing states because of inner selfishness. The greater the selfishness, the greater the amplitude of the oscillation. When one works for the sake of others, for the sake of morality, the mind becomes more stable. A person who is diligent only for personal wealth and advancement will, upon failure, become lazy and disheartened. But one who is diligent in order to serve and help others possesses a strength and perseverance that no adversity can shake.

"The greater the selfishness, the stronger the inner oscillation."

In the Buddha's teachings (Dharma), there are certain qualities of the heart that never reverse, as they belong to the path of liberation. These are:

- The mind of compassion – loving others without expecting reward - The mind of forbearance – enduring suffering and insult while remaining at peace - The mind of humility – respecting others, free from arrogance - The mind of vigor – diligently guarding the mind at every moment - The mind of thoroughness and tolerance – both discerning and magnanimous

These qualities act like the stabilizing cord of a pendulum, preventing our mind from being tossed about.

**The Skilled Practitioner Narrows the Swing of the Pendulum**

Practicing the path of the Buddha is not to become someone with a dazzlingly joyful spirit at all times. It is to gradually narrow the amplitude of oscillation between opposing states, until the mind rests in stillness. Some who have practiced for a few years can clearly see they no longer chase after joy or sorrow; their mind remains serene like a calm lake. This is not apathy, but the beauty of a purified mind.

"The true value of spiritual practice in the Buddha's teachings (Dharma) is to gradually narrow the amplitude between opposing mental states until it comes to rest in stillness."

Begin today: before words of praise, let your mind not be flooded with joy; before words of blame, let it not sink into sorrow. When you see someone being good to you, observe whether they are equally good to others. When you feel your temper rising, pause and observe the pendulum within. Gradually, you will find your mind becoming composed, strong, and peaceful.

Life may not be inherently fair, but we can grant ourselves a purified inner world. This is the path of the practitioner, and of all who seek true happiness.
