Possible Potential Buddhist
My teacher always insisted, there's no conflict between Buddhism and the rational world, no conflict between Buddhism and the scientific method. He said, one can be saint and a successful businessman. The Buddhism's teaching on karma, emotional intelligence, and the nature of phenomena, are all continuation of the rational approach we know from western discourse.

The only difference I know of is in the goal. The implied goal of mainstream culture these days is what's known as success: personal and professional realization. The goal of Buddhism, in Theravada school is the peace of Nirvana and in Mahayana school is the endless service to the world and people. And yet, my teacher said, you can have it all: peace, service, and realization. 

The only choice we have, he said, is to try and achieve something greater, and what can be greater than spiritual realization? The other alternative, the life of mediocrity, is not a serious choice.
