For me personally I have a high energy level. I was highly competitive. That helped, but I am always inspired to do more. I try to do more all the time, so I don't worry about my energy level being too high and it rarely ever gets too low. For yourself, if you are in doubt about whether your energy is too low or too high, push it up, don't ever experiment by pushing it down, bring more energy if you think you can, do it all the time. If you find out you have used up too much energy, you are just going to collapse, and that's okay. It's like going back to the training. Some training sessions we will get really exited, and we will push this one, you know this is really going. For example, if we're swimming and our swimming times in the training are super close to our actual fastest times, we want to push harder. You can't do that in training all of the time, you get totally exhausted by the end of it. On occasions, we push.
When it comes energy, when you're ever in doubt, try to push it up, try to increase it by using any good method, whatsoever to do it. This is why one reason why we encourage Kalyanamittas, good spiritual friends. Some of you who have known each other for years, you use Skype to talk to each other. Others of you will make new friends at the end of the retreat. If you don't have friends here yet, get together, consider communicating regularly if you don't have a sitting group in your hometown, a place you can join others, you can still do it, Skype on a computer on a regular basis, that can give you energy in a lot of different ways.
The Knowledgebase that we have prepared has over eight hundred questions and answers already. A lot of our students are using the knowledgebase to stimulate their own thoughts. They read a question, they don't look at our answer, they try to figure out what the answer is. If you have a partner to do it with it's really good, it brings about a Dhamma discussion. You both try to figure out what the answer is. By the time you both agree to something that would work pretty well, then you look at the answer by either Rosemary or myself and see how it compares. It might be slightly different but may still be okay. This is another way to stimulate, stimulate, get more Dhamma in there, get input from other meditators, other friends, get your energy up if needed.
