Instead of just reading Buddhist teachings or thinking about them, put them into full-hearted practice.
"Compare practice to a bottle of medicine a doctor leaves for his patient. On the bottle is written detailed instructions on how to take the medicine, but no matter how many hundred times the patient reads the directions, he is bound to die if that is all he does. He will gain no benefit from the medicine. And before he dies he may complain bitterly that the doctor wasn’t any good, that the medicine was worthless, yet he has only spent his time examining the bottle and reading the instructions. He hasn’t followed the advice of the doctor and taken the medicine.
… Doctors prescribe medicine to eliminate disease from the body. The teachings of the Buddha are prescribed to cure disease of the mind; to bring it back to its natural healthy state. So the Buddha can be considered to be a doctor who prescribes cures for the ills of the mind. He is, in fact, the greatest doctor in the world.”
