Btw, were you trying to quote Jesus here? If you meant John 14:2 every translation I have checked has not mentioned "many realities" in this verse nor close to it. Nor do I recall any place in the Christian bible linking "many rooms" or "many realities" to something that those who have eyes are expected to see...but perhaps I have missed something? Or perhaps you weren't trying to quote Jesus here?
I was speaking from my own words and experiences while at the same time understanding what Jesus meant in His teachings.
There was much that Jesus did not come out and say as He did not want people to strive to obtain the abilities or gifts which He was able to perform. He wanted people to grow closer to God where the abilities are a natural attribute of the person’s level of spiritual development of their soul.
Many people try to get me to teach them how to do what I do. My response is to read the Bible, pray and meditate on its meaning. If you obtain the abilities but do not grow you will be like the people who used Jesus’ name and He did not know them. The ego self develops pride in the abilities as it takes ownership and forms an huge identity around them. This creates separation from God as when a person is full of themselves, they have no room for God. This is why dying daily or emptying self is so important.
If a person holds onto an ability as an identity, it shackles them from growing higher. The rung on the ladder that you use to climb will hold you back if you cannot let go of it to climb higher.
Back to the many mansions... Each level of consciousness in the Tower of Babel is a different room with different abilities and perceptions. As you follow commandment number one, Love God with All..... you grow closer to God and reach the higher levels. Some levels are very difficult to experience while still in the physical body. My near death experience gave me a taste of those levels, and then I was sent back into my body with the knowledge that I could transcend self while still in my physical body if I followed Jesus’ teachings.
Just to give you a simple example of why Jesus’ teachings are so important to different perceptions of your reality. In depression, you can find your consciousness at such a low level that even mole hills in front of you appear to be mountains. With prayer and meditation and cleansing your soul while staying focused upon God, you can raise your consciousness perspective to the level where even mountains appear as mole hills. Each level is a different perception of your reality. Through prayer and meditation and staying focused on Loving God, you can have your consciousness transcend the physical body and be born of the spirit. At that time you begin to perceive a whole new reality again. (You truly become born again) Just as your reality when you were in your mother’s womb was limited to your environment, and when you were born of the flesh you began perceiving from your physical body senses a whole new reality, when you transcend the body and begin perceiving from your soul or spirit you have a whole new reality, right here in the same physical space. That is why Jesus said you must go within to find thy Father.
Jesus did not take credit for His abilities. He always treated them as His Father working through Him as He always strived to be “One with His Father.” That is the exact reason Jesus wants you to take Communion and be “One with Him.” Sounds very Buddhist doesn’t it? They were both saying the same thing.
