Cycle of birth and death [An old Kannada saying.]

8400000 jeevarashiyannu daati banda ee sharira. 

Translation: To obtain a human body, you should pass through all 84 Lakh forms of life.

Which means God failed 84 Lakh times before creating a masterpiece ie., Human.

It is said world is a drama staged on earth and Life in different(84L) forms is manifested and live it's lives vibrantly. (Live love laugh experience life) Earth is a vibrant stage designed for life. A magical wonderland. Basically manifesting life on earth and letting it live, ensuring life is always there on earth in some or the other form.

{Non material body combining with material body to become A Being is manifestation of non material body}

Basic drill is to come on stage, play the role, and go back... so God started creating and sending creatures to earth. He sent the first one L1 (life no1) with utmost joy and celebration. So L1 came on earth in a certain physical form and immersed in the character, he forgot he had to go back. He did not  even know he had to find out why he was here. So God sent another one L2, slightly improved version hoping it would come back, but the result was the same; it did not come back either. Thus he continued to create more and more creatures new and improved every time but to no avail he kept on failing. He did not give up, he went on and on and on.

Now God is confused why isn't no one coming back.!? And stupid creatures don't even have characteristic features in them which will remind them of the truth so that he can seek his truth.

So now He knew where He was going wrong.

All forms of life he sent on earth did completely get into the character they played and lost track of their origin/home and unfortunately never came out of their character and periodically shifted from one character to another. So He thought of designing a technology which would always keep poking them so that they will know that there is some mystery to unlock.

It is then that God created a masterpiece that is the Human Body and put some "consciousness" and some "decisive ability" in it so that he can go in search of truth and finally come back. [In simple thinking ability.]

Every form of life was important and unique and not inferior in any way. They were complete and remarkable in their own way. So, each life had to pass through all 84 Lakh creature forms to become human.

Before sending it again, he said to life, "I'm giving you the masterpiece (guiding star) technology, make most use of it, get past it and then find your way out".

After human species there will be no further physical evolution because Human was made such that finally spiritual evolution can occur.

Body is a little fragile, because obviously there's life running all over inside. It has some requirements to make it work well for you, like, Eating Sleeping Mating and Defending to keep it grounded and attached to life. These were just, either regular or periodic, arrangements for the body to LIVE and realize whatever and go back.

And possibilities/threats by which u can lose or gain human body were, Birth-Death, Old-age and Disease. {Which are actually the ones you have to go beyond and overcome}

So now, Life first comes to the back stage, that is a womb, gets the costume, wears it beautifully, does all the makeup required and is all set to perform/live. Once life was out of the womb and started getting into the character of humans, it again forgot to get out of character.

Now God's new technology worked and it gave humans a lot of ways to grow higher and deeper. In the beginning it was easy for humans to do it all.

After a certain point. There was a group of humans who decided not to follow the technology, saying it is a challenge to overcome the defects (Which were supposed to be growth milestones). And they made all other humans follow the group.

So they started making policies procedures rules regulations etc

And approve only one style of living prescribed by them.

But in every human there was a corner which always poked. But they were denied from pursuing it, in simple cease to be natural.

now poking won't stop ...

1. So few humans started pursuing it secretly on their own and not disclosing it to each other.

2. Very very few humans refused to stop and they pursued life openly and not secretly.

3. Rest of the humans purposely followed the ban and others blindly followed the ban.

So, the 2nd category went back to God one fine day. God was happy his technology worked but saw there were only a handful of them who came back. So he sent them back to bring others back.

Now 1st category went back to god one day. God was unable to identify them because they were disguised obviously as they  lived in secret. But then He is God he knows who was who, and appreciated that they managed to live there (between cat 3 people) and come back as well.

Lastly 3rd category were the majority, so they were the rule makers and they instead of going back to God, brought God himself into the stage, made him sit in a corner and watch them play their roles.

God was horrified!

Or you can put it simply as a video-game until you finish/realize your goal you keep coming back (even after you lose all lives, it will be restored) to the same drama of life...
