I am training in the Pa-Auk method. However, I have heard that even at the Pa-Auk meditation center, entering the first jhāna is difficult. This makes me wonder whether it is possible for a layperson to attain jhāna. If a layperson practices meditation for about 2–3 hours a day and minimizes external interactions as much as possible, would it be possible to enter jhāna? If not, how much practice would be necessary?
