Action Then Feelings?

Before we started the lovely source sheet about korbanot, I always thought that bringing an animal as a sacrifice was pretty random. I certainly did not think that the animal had any symbolism or importance behind it. However, the Sefer Hachinuch, a book explaining the 613 mitzvot, changed this. The Sefer Hachinuch explains that animals lack a divine purpose. They only live to fulfill their desires. What causes us to sin are our desires and lack of ability to refrain from giving into base animal instincts. Therefore, if a person continues to act like an animal, he too will deserve death. The Sefer Hachinuch concludes that it is symbolic to have an animal as a korban because the reflection needs to be an understanding that sin is acting like an animal. So, we 'squash' this animal instinct. This fits the 'theme' of the explanations that the Sefer Hachinuch gives: "Acharei Ha'Peulot Namshech Ha'levavot" which means first take action and then the feelings will come. After one gives the animal as a sacrifice, his desires are 'burned' and then he can reflect on his mistakes and strive to improve on himself. I find this 'pitgam' very interesting. I don't agree with it fully. Sometimes I do believe that the action must come first, however, sometimes you need the feelings to do the action. For example, if you don't have the 'feelings' or inspiration to do a mitzvah then when you do it, it's not rewarding at all. It's like doing a mitzvah without really wanting to do it. This is why sometimes I need some sort of motivational experience to help me preform the action to the best of my ability. So, maybe we need the 'feelings' first to ensure that the sacrifice (action) is as successful and meaningful as it can be?
