Sages seek heart but not Buddha, fools seek Buddha without heart; Wise men adjust their mentality, fools adjust their mentality. What do you mean?

The meaning of this sentence is that saints pursue inner practice instead of blindly asking for Buddha's blessing; Fools blindly ask for Buddha's blessing and don't pay attention to inner practice. A wise man adjusts his heart, not just his body; And stupid people only adjust their bodies, not pay attention to their inner adjustment.
