What is the kingdom of heaven?  “Except you become as a little child you shall not see the kingdom.”  Jesus said “The kingdom of God is within”.

The child spirit is within.

Here is my personal interpretation of the verse above:

I honor the innocence of my spirit, a spirit that is filled with wonder and imagination.  Who sees no separateness, only connectedness to all things living.  With my child-like spirit, I enter a magnificent place called heaven, nirvana, pure JOY.  My spirit dances and plays on God’s playground, some have named heaven.
