This is not at all possible other then giving away your own conscious energy (on the other side)for purpose of Karma Debt. Your consciousness cannot in any way go into something that is not compatible. It is the same like within the other worlds on the other side (Heaven). You cannot enter the other world before understanding and thus this is why we have everlasting wheel or Reincarnation. Everything around us and you yourself has a resonance and so this is understanding of what your knowledge to what you know to be so. To go beyond this, you have to experience and then you can graduate to another world (frequency of Understanding).
This is a demanding question to answer without knowing the whole result. In Hinduism teachings they say if you kill a Mouse and so thou shall you become a mouse in another life. This is not completely true as your consciousness is huge and it cannot inhabit a Mouse as this is called – Transmigration. In most cases the scale for Souls to Follow is an upward trend and not downward. Once a Human you cannot go into lesser forms unless the soul decides to make division split to pay for Karmic Debt. There is a sense that a portion of your consciousness can agree to do this but it would doing so knowing it would lose it’s mass. This is where smaller forms of life can be born from these division splits. It’s demanding to talk about this as our Human brain is not capable of totally explaining this process. I feel that I should discuss about this question as it has to be understood first then simply talk about.
If you kill thy own Brother and so your brother will kill you and this is Literally true. It will happen is some way or another that this person that you did wrong to will kill you. This can take 5 years or thousand years but it will happen. It’s not punishment as per say, this is just souls balancing them self’s out (energy). This of course is geometric inclusion anomaly as I like to call it. I still don’t understand to this days how these circumstances come to be?
Well in conclusion – no you cannot be born as mouse or spider but energy can be given away (as a Division of Payment) and it you will form life. If someone tells you this they are just reading these from books and not real life. It is most likely that these text were some how trying to scare people from not committing any deaths onto animals (not that it’s okay to do so). It is like saying in Christian Belief “that if you kill you will go to Hell” (and that never happen like this). If you kill thy brother then you will just downgraded your frequency of awareness. My source is from within and so this is why I know.
