Observe what comes and goes and the space in which that occurs. Prioritize the space. Sit down, hold still and find out who you are. That is the basic instruction.
Set aside time for retreat practice. It could be a short block of time like four hours or for multiple days. It could be solitary or with a group. Whatever your meditation practice is, it is important to retreat from your everyday busy world and take some time to look at your mind. Receive whatever arises…and don’t evaluate. Whatever you can do, schedule it ahead of time and just do it.
You can’t really think your way out of addictions. Rather than talking about recovering from addictions by controlling behavior, Sokuzan teaches addiction awareness meditation. Through sitting meditation practice, by training the mind to observe what is happening in all of the sense fields, mind and body not separate, we are training awareness to see situations as they arise so what to do becomes clear without evaluating or trying to get rid of anything. You need to spend a lot of time training your mind. Dedicate at least an hour a day to your practice.
A teacher may help a student access deeper levels of consciousness by facilitating regression to another time and place. Exploring in this way, without believing, disbelieving, or shutting down on whatever arises in mind can be a way to work with intense difficulty and ease suffering. Here Sokuzan gives an example of working with deeper consciousness during a meditation interview.
