This is too big for right now. I will mention that in the 20 day retreat we have a second type of Parami meditation, and it is to reflect on the Paramis in pairs. There are Ten Paramis and there are 45 different pairs. The meditation that we give is to actually take each Parami one at a time and consider how they relate to each other. Check if there is kind of an order, maybe one comes before the other. Say with Determination and with Energy: we make a Determination "I am going to stop smoking", then we bring forth the Energy in order to stop smoking. So some Paramis work in an order, one comes before another. Some Paramis definitely need a good balance. For example, Compassion/Lovingkindness with Equanimity, they are two different Paramis. Last night I talked about Compassion and Equanimity in regards to having a balance.
So some need a balance and we advise you to reflect for yourself on this. Take them all in pairs, it takes longer than one sitting period, and go through them as deeply as you can. Try to see each one from different angles. You take Wisdom, you take Renunciation, put them together. You take Generosity, you take Patience, put them together. And it may help to have it as a list in front of you. But to go through them all as pairs is very helpful. As to the question then - in what way do they balance the best? It will come out in your own understanding and hopefully more than just understanding. Balance will come out in your understanding. Also look at how they actually build on each other as well, things like that are very helpful to look at as well.
Now, in this light you might like to know, for those of you who never heard about it, according to the scriptures our Buddha, Siddhartha Gautama spent six years as a meditator, he became enlightened, discovered the teachings and so on. As you know Buddhism talks about rebirth, and supposedly 500 lifetimes ago our Buddha made a vow. He was a meditator in the woods, he met another Buddha who was alive at that time, he made the vow that he wanted to become a Buddha, also. Then after he finished with the vow, the Buddha actually looked in the future and said, "Yes, good, you are going to be a Buddha." When he was done he went back to his meditation hut up in the hills and, as recorded, what he did then was ask himself, "Well, now I made this vow, what am I supposed to do?" Perfect the Ten Paramis? This is exactly what he did. He started reflecting on them day and night for I don't know how many days. He looked at them in one way, he looked at them in another way, the Ten Paramis were his job. For a Buddha, if you don't know, the Ten Paramis have to be perfected, all 10 have to be perfected in order to be a Buddha. For other enlightened people called Arahants, they only have to get them to a very high level to get enlightened, just to a very high level. But for a Buddha, in order for someone to become a Buddha, all 10 must be perfect. So it is written that the person who made the vow to become our Buddha, at that time, after he made that vow, he meditated on the 10 every different way that he could for many days before he then started working on them.
