There are people who are sincere, and truly believe in helping others. There are also people who are only concerned about themselves, and do not care what others think about themselves. There are also people who pretend to care about others, but their actions reflect their selfish purpose.
In the Tip of the Writing Brush is written:
Since it is God who began the world,
there is nothing unknown to Me. 8-11
The innermost heart of everyone in the world
is all reflected to God. 8-12
Whatever is in your heart, God clearly sees. You may be able to fool yourself or others; but you can not deceive God. God sees your thoughts. Whether you believe in heaven or heaven on earth, your future happiness depends on your thoughts and actions. It does not depend on our earthly possessions, and you cannot depend on material wealth to cause happiness. It is only the pure mind that will lead to joy.
How do we obtain this pure mind? Sweep greed, arrogance, and self love from your mind. If this is difficult, pray and ask God for guidance. When all mankind is pure from the heart, the world will experience the joyous life.
