How did Phra Ajaan Sao teach? If it so happened that someone came to him, saying, "Ajaan, sir, I want to practice meditation. How should I go about it?" he would answer, "Meditate on the word 'Buddho.'"
If the person asked, "What does 'Buddho' mean?" Ajaan Sao would answer, "Don't ask."
"What will happen after I've meditated on 'Buddho'?"
"Don't ask. Your only duty is simply to repeat the word 'Buddho' over and over in your mind."
That's how he taught: no long, drawn-out explanations.
This goes along so well with a story of the teachings of Ajahn Dune Atulo:
Gifts he left behind wrote:A middle-aged lady once came to pay respect to Luang Pu. She described her situation in life, saying that her social position was good and she had never lacked for anything. She was upset, though, over her son, who was disobedient, disorderly, and had fallen under the influ-ence of every kind of evil amusement. He was laying waste to his parents’ wealth, as well as to their hearts, in a way that was more than they could bear. She asked Luang Pu to advise her on an approach that would lessen her suffering, as well as getting her son to give up his evil ways.
Luang Pu gave her some advice on these matters, also teaching her how to quiet her mind and how to let go.
After she had left, he commented, “ People these days suffer because of thoughts.”
