In the seventeenth chapter of the Samyuktagama Sutra, there is a record of the Buddha asking his disciples what the difference is between ordinary beings and sages, as well as the differences between their sensations of suffering and happiness, The Buddha told them that the body of ordinary beings experience suffering and are trapped in worry and anger as a result, bring more pain to the mind.
The sages also have human bodies that experience suffering, but they are not worried or distressed, and thus the mind does not experience the sensations of the body. The difference between the two is that ordinary beings are affected by the Five Desires and give rise to the Three Poisons of greed, aversion, and ignorance, while the sage is not.
Consequently, we should rely, in our daily lives, on Right Mindfulness, Right Diligence, and the Right Path to conduct ourselves. We should, through applying the wisdom of self-reflexivity, develop our hearts of endurance, humility, sincerity, purity, serenity, compassion, forgiveness, equality, forbearance, repentance, gratitude…so that we do not give rise to various types of negative emotions. Only if we manage our emotions well, will we be able to recover the command of our hearts. Only then can we be masters of ourselves.
