I would assume that you are interested to know why people CHOOSE this religion.
The most salient point in Buddhism is the FREEDOM to think and analyze. The Buddha encouraged his followers to analyze his teachings. Only if they agreed with them should they accept and follow. There are no dogmas and commandments, forcing people to accept. The basic 5 principles which Buddhists follow are universal values. They are as follows:
to refrain from killing; from stealing; from committing sexual misconduct; from telling lies; and from taking intoxicating substances.
The Buddha preached COMPASSION for all beings. Non violence is the essential theme.
The Buddha revealed the universal truth of the nature of this world and this existence. His explanations were based on facts that we could analyze. His revelations have been proven to be consistent with subsequent scientific discoveries.
The emphasis on cultivating and training the mind is yet another salient point which people choose Buddhism. A tamed mind is a gentle mind. He who has tamed his mind is a person who can live a peaceful and harmless live. He is the master of his mind. He is not one who is a slave of his mind leading to greed, hatred, and delusion.
