Heaven is eternal and Earth everlasting. They can be eternal and everlasting because they do not exist for themselves, And for this reason can exist forever.
If a thing happens once, it can happen again. If any human being has ever realised perfection, we too can do so. If we cannot become perfect here and now, we never can in any state or heaven or condition we may imagine.
Sages do not accumulate for themselves. The more they give to others, the more they possess of their own. The way of Heaven is to benefit others and not to injure.
The energetic action of the times develops individualism, and the religious appear isolated. I esteem this a step in the right direction. Heaven deals with us on no representative system. Souls are not saved in bundles.
