QUESTION : Wasn't it irresponsible for the Buddha to walk out on his wife and child?

Lord Buddha Taking Last Look On Family

ANSWER :  It couldn't have been an easy thing for the Buddha to leave his family. He must have worried and hesitated for a long time before he finally left. But he had a choice between dedicating himself to his family or dedicating himself to the world. In the end, his great compassion made him give himself to the whole world, and the whole world still benefits from his sacrifice. This was not irresponsible. It was perhaps the most significant sacrifice ever made.
