Some inscriptions regarding the Fasting LTE

This is the first time I have done a 3 day fast from food and talking. I can wrap the experiences I had and the things I learned during the Fasting LTE into four points, which I have listed below.
I learned in a sense deeper than words, that:
I need to bring everything, every thought, every item and every notion of personal possession to God
I need to be honest with God in prayer
I need not focus on myself or pity myself but focus on God
Spending time with God in His Word and His creation is refreshing beyond explanation
I think that fasting is monumentally purposed for developing the proper mindset God wants a person to have. In my opinion, fasting is directly connected to getting closer to God because God wants you to be learning from Him and God wants not only to speak to you but He desires that you hear from Him when He is speaking and not just that but He wants it to change you and that change will give birth to healthy habits and a Godly lifestyle. So, in order to get closer intimately to God a person needs to spend time with Him and connect with Him by not only listening but responding as well and the only way to do this is to have the proper mindset which I believe God uses fasting for. Those who fast from food are choosing to put to death the deeds of the body in a way. I don't necessarily think that is what that verse was meant to portray when Paul said in Romans 8:13 that if you live according to the flesh you will die but if by the spirit you put to death the deeds of the body you will live. I do think this verse is huge, but not for my specific point here but I will tie it in. Given that the average person wants to live, I am going to say that according to this verse we need to put to death the deeds of the body and not by ourselves but by the Holy Spirit that dwells in God's temples. Now, to put to death the deeds of the body, is stating that the deeds of the body, our sinful nature, need to die and we a supposed to kill these bodily deeds with the Holy Spirit's assistance. If something is put to death, it has no life and what brings life? Oxygen, water, sleep, and food. Now what if we took one of these life necessities away for a while in order to put the deeds of the body to death. As this occurs, a person might actually be able to still their soul and mind to a peaceful place of openness to God's voice. Therefore leading to hearing from God, which leads to change for God and A life lived in the Spirit with more receptiveness to God. If we were perfect we might not need to fast so much but since we are not a fast similar to this might be very beneficial every so many months/weeks.
The bible talks about fasting a few times that I can recall.
Isaiah 58:6 says "Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke
There is a story about where Jesus said "This kind only comes out by prayer and fasting" I presume, meaning that prayer and fasting will be important in getting a person from where they are to where hay need to be.
After all the words that can be said the greatest truth I came away with was that God is my only satisfaction.
