Basic Understanding of Soul Evolution
If the involuntary kriyas have started in you, it means, you should have been a different personality altogether since your childhood.
You should have been more religious or having faith and love towards the divine or some even, are so practical and rational that they do not believe something they do not see. Such atheists also would get these involuntary kriyas. They get because, they may not have faith in god and all but, their way of living life would be more harmonious with the LAWS OF NATURE. By following the laws of Nature one gets the cosmic vibrations of Nature. Some of you should have been quite positive thinking, universal thinking. So, you would love people and help people naturally without expecting anything. Some of you would think about others and pray for others. Though you may have these qualities, you would carry your own traits, negativities and weaknesses.
You must have started meditation in your life for peace and to get rid of your problems. Though you were not a serious meditator, these kriyas would start in you. You would have started meditation practice probably to get rid of stress, or to get rid of your problems in life or probably to get rid of the health problems and so on.
The point you should understand is that, the soul evolution happens for several lives together. This whole atmosphere or all world is like the womb of Cosmos. The bodies of all souls die within the same womb of Nature and they are again merged back into the same womb of Nature. They are born within the same womb and follow the cycle of evolution through births and deaths. But they can never get out of the womb of Nature. Because of the bondage towards the womb of Nature due to Karma (that is again based on Traits or Sanskaras and their energies, attachments and desires) they are born within the same womb. Getting out of the womb is called LIBERATION or FREEDOM to the soul. The karma that they owe to this world (which is the womb of Nature) does not let them get out of that cycle.
There is a big algorithm by which the whole womb of Nature works. Knowing that algorithm and understanding that algorithm does not happen for a man directly. As per the algorithm of that womb, there is a special one who actually liberates the souls out of the womb of Nature. That special one is nothing but God as per religions.
But, in reality you are also that GOD. You are not an individual one, because of forgetting this, (due to awareness of the wrong consciousness) you keep encircling in that womb of Nature itself. Now, God or the pure-self manifests in the form of Guru, to show the way to liberation which is nothing but showing the way to get out of the womb of Nature.
Guru is not a physical body but he is the cosmic self. He comes down in the form of physical Guru with Anugraha (grace) to get you out of the womb of Nature. Do not have wrong beliefs and opinions that, Guru will introduce you to God or Guru is a middle man between you and God. Guru himself is God (Guru Sakshat Para Brahma which is not told in a simple way but in the real sense it is told)
Now in your case, what is happening is, both Nature and Guru, work together to liberate the souls. In a simple way to say, Guru is the soul father and Nature is the Mother. Both mother and father work together, to get the children out of the BONDAGE of the womb of Nature.
For your clear understanding, I present you here the pictorial format. The green color egg shaped one is like the womb of Nature and the circle inside is the evolution cycle from A to Z. The soul goes through several lives of evolution, through practical situations in lives. Say, in previous life if you were evolved to level “S”, in this life, you will again be connected to the point “S” and from there; your evolution will start again, in this life. The womb of Nature works like a HOST and it is responsible to sustain all souls in it. It has its own power, energy, authority and laws. It works based on its own algorithm which no souls can understand. In case, you were evolved well spiritually in previous life, the womb again connects you to that point in the current life. So, the womb connects you to that point and as a host it is also responsible to connect you to the GURU who will evolve you and get you out of her womb. The Nature cannot get you out of her womb. Nature needs her companion or husband or partner who is a PURUSHA (the purest one the origin one) who comes in the form of Guru.
