1. The Founding Master said, "Not all scientific studies are constantly in use; however, if you learn how to use the mind, this study can be utilized without a moment's interruption. Therefore, mind practice becomes the basis for all other studies."

2. "A practitioner of the Way seeks to know the essence of the mind in order to achieve freedom of mind, to realize the principle of birth and death in order to transcend birth and death, and to understand the principle of transgressions and blessings in order to control them at will."

3. "If one's mind is wholesome, whatever one does is wholesome; if one's mind is unwholesome, whatever one does is unwholesome. Thus, the mind becomes the basis for everything wholesome and unwholesome."

4."If a person whose mind is crooked has a lot of money, knowledge, or power, then those things become the basis for transgression and unwholesomeness. Only after one's mind is upright will money, knowledge, and power be transformed into eternal blessings."

from The Scriptures of Won-Buddhism, Chapter 11, v. 1-4

15. Once, when the Founding Master was residing at Pongnae Cloister, an old couple was passing by and commented that their daughter-in-law was so ill tempered and disrespectful that they were going to Silsang monastery to make a buddha offering about this situation. Upon hearing this, the Founding Master said to them, "How is it that you know to make a buddha offering to the buddha image but not to the living buddha?" The old couple asked, "Where is the living buddha?" The Founding Master answered, "The daughter-in-law who lives at your home is the living buddha. Since she is the one with the prerogative to be either filial or unfilial, why don't you try making an offering to her, first?" They asked, "How should we make such an offering?" The Founding Master replied, "With the money you were going to use for the buddha offering, buy her a gift that she would really appreciate and treat her with the same respect that you would for the Buddha’s image. Then, depending on how sincere you are, the effect of your buddha offering will appear." When the couple returned home, they did as they were told and ultimately, some months later, she indeed became a caring and virtuous daughter-in-law. The old couple returned to the Founding Master and thanked him over and over again, and the Founding Master said to his disciples sitting beside him, "This is an example of the realistic worship of Buddha offered directly to the actual source of misery and blessings."
