It is seldom that a Buddha appears in this world. When a Buddha does appear, He attains enlightenment, introduces the Dharma, severs the net of suspicion, removes the lure of desire at its root, and plugs the fountain of evil. Completely unhindered He walks at will over the world. There is nothing greater than to revere the Buddha.
Buddha appears in the world of suffering people because he cannot desert suffering people. His only purpose is to spread the Dharma and to bless all people with its Truth.
It is very difficult to introduce the Dharma into a world filled with injustice and false standards, a world that is vainly struggling with insatiable desires and discomforts. Buddha faces these difficulties because of His great love and compassion.

Buddha is a good friend to all people. If Buddha finds a man suffering from the heavy burden of worldly passions, He feels compassions and shares the burden with him. If He meets a man suffering from delusion, He will clear away his delusions.
Like a calf, which enjoys its life with its mother, those who have heard the Buddha's teachings are unwilling to leave Him because His teachings bring them happiness.
