How soon after death do you go to heaven?

Does anyone of earth go immediately at death into the heavenly sphere?

When I speak of heaven, I refer to the place and condition in which I now exist. If that is what you mean, then I say―yes―to your question. But if you refer to the Holy of Holies―the Central Sun―the dwelling place of the Most High spoken of in the Hebrew writings, then I would say―no. 

No one of mortal birth can enter therein until he is purged from every taint of earthliness―

Not even the spirit of the child whose breath was stopped at birth can enter immediately into the glorious place, for that innocent has by its mortal birth inherited certain earthly tendencies, and these by a long course of education must be rooted out, and the strength and virtue, which are gained by a life of trials on earth must be acquired here by a slower process. 

Trials experienced in the body are much more advantageous in the education of man than the discipline of spirit life. 

The longer man lives on earth the better, and if he has improved the opportunities of his long life wisely and well, he is blessed indeed.
