"Through your heart you will, after death of your body, step out into God's endless space and, depending on the nature of your heart, you will find this to be either heaven or hell.
For there is nowhere a specially created heaven or hell, but all that goes forth only from the human heart. And thus, everyone prepares for himself either heaven or hell in his heart, depending on whether his actions are good or bad, and he will be living according to his belief, his will and actions, since his will was nourished by his belief, thereby passing into action.
Let everyone examine the inclinations of his heart, and he will easily discover what kind of spirit prevails in his heart. If his inclinations draw the heart and its love towards the world and he feels within him a longing to become great and respected in the world, if the heart that is inclined to become proud feels discomfort with poor mankind and has the urge within to dominate others, without having been chosen for it by God, the seed of hell is already lying in the heart and, if not overcome and nipped in the bud, will obviously prepare for such a person nothing but hell after the death of his body.
However, if a man's heart is full of humility and he feels happy to be the least among men, to serve all and disregard his own self because of his love for his brothers and sisters; if he willingly obeys his superiors in all things, for the benefit of his brothers and loves God above all, then, in his heart, the heavenly seed grows to a true and eternally living heaven. And this man, who thus has already all heaven in abundance in his heart, which is filled with true faith, the purest hope and love, can after the death of his body not possibly get anywhere else but to the Kingdom of God which he has already carried in his heart in all abundance for a long time." (Great Gospel II/8, 6 on; VIII/18, 2 on; X/197, 10 on; VI/244, 7).
