Begin by reading the lectures the accompany each type of meditation so that you understand the how and why of the particular meditations that we’re working on. I would suggest doing NO MORE than one new meditation a day, however, you can get a lot of benefit by stretching this practice out and focusing on one new meditation a week. Digging deep into one style of meditation can lead to quick improvements in the associated skill.
You do not have to meditate every day. I would suggest starting with 3 times a week at minimum to prevent you from losing any progress that you’ve made but working more than that isn’t necessary unless you want to create a daily practice out of it.
Begin your first meditation with a timer running. Start the timer, try the meditation, and the first time you find yourself thinking “how long have I been doing this”, “how much longer do I have to do this”, or “I wonder if I left the stove on” stop the timer. That is now your base time (and no, I don’t care if it’s only 40 seconds, that’s where you’re starting). That’s the time I want you to use when you sit down to do your meditation.
Set your timer to that, meditate until the timer goes off, and you’re done for that meditation session. After using that time 3-4 times you can try increasing that time a bit. If you started with 40 seconds, try 1 minute. If you started with 1 minute, try a minute and a half. It’s ok if the first time you work with this new time you struggle a little bit toward the end of the meditation. Keep trying until the timer goes off and give yourself a pat on the back when you’re done.
Once this new time begins to feel pretty easy, it’s time to increase the length again. In this way, you’ll increase how long you can comfortably meditate very gradually and soon you’ll be comfortably meditating for much longer than you initially thought you would be able to.
Do this process for each meditation. Every time you sit down to a new meditation, record a new base time for that particular meditation and start there. As I said earlier, these meditations are designed to work certain magical skills and you’ll likely find that you can focus on some of these meditations far more effectively than others. I suggest keeping track of each meditation and the times you’re currently working with in your journal or grimoire, that way you don’t forget what time you were using before and overtax yourself on accident.
It can also be helpful to journal about your experience each time you sit down to meditate. Voicing your thoughts, frustrations, impressions, and feelings about your meditation session can give you some great insights into your internal world and help you improve your meditative practice going forward.
