(9.141ab) Through these various lines of reasoning,
We have established that production does not occur without a cause,

I am not entirely clear why Shantideva once again explained how there is no such thing as production without cause. Perhaps this was his way of giving the reader a breather from all of the extremely intense logical arguments. We all understand relatively easily that there is no such thing as production with no cause.  Perhaps he is trying to just remind us of something that we already understand so we do not get discouraged by the other more difficult arguments. I do not know if that is true or not, but it is one way of understanding why he repeats himself on this point. I am sure there are other reasons we could think of, but I do not think it matters.

In Joyful Path and other texts, Geshe-la explains the patience of definitely thinking about Dharma. The point is this, realizing emptiness and other Dharma subjects can be difficult. At first it makes absolutely no sense because it goes exactly contrary to everything we have come to understand about the world. Dharma is exactly opposite to our normal way of understanding things, so it is normal that when we first encounter it, we struggle to understand its meaning and may easily develop misconceptions.

Sometimes when we see all of these complicated debates we can easily become discouraged thinking we will never understand emptiness and we certainly don’t understand why Shantideva and Chandrakirti go back and forth with so many seemingly intricate and almost meaningless philosophical distinctions. We wish we could go back to studying subjects that warm our heart like love, compassion, and our precious human life. This is normal, and we should not expect it to be any different. It is not a failure on our part that we sometimes get discouraged.

But it is not enough to say it is normal to get discouraged, we must find a way of overcoming our discouragement. In Oral Instructions of Mahamudra, in the section on the great preparation of purification, Geshe-la spends almost all of his commentary talking about the need to purify the negative karma that gives rise to our wrong views. Since we have been thinking in samsaric ways since time without beginning, we have accumulated a tremendous amount of tendencies similar to the cause that think in non-Dharma ways. This is the fundamental reason why we find it difficult to understand Dharma. If we want to reverse this situation, we need to purify this negative karma and, through the force of our effort, gradually build up new tendencies similar to the cause that are consistent with the Dharma. Then later it will become easy and effortless for us to realize Dharma things, and difficult for us to believe non-Dharma things.

In the meantime, we simply need to be patient with the process. We should not be discouraged but be more like a child that play doing something that is possibly beyond their capacity, but they are excited to try because they know that they are growing up by doing so.
