I assume that the self we will be in Heaven is our most authentic and best self – call it the true self. This true self will be void of all sin, free of death and entropy, fully aligned with God and Creation, and capable of intense and immense creativity.
With this in mind, examining what our true self would do and want to do in Heaven may be a useful and revealing thought experiment that may open many conduits of potential learning.
At first, the thought experiment will likely be far more successful at uncovering false selves than honing in on what the true self would do, but this widdling away process can teach us much about our false selves and, perhaps, bring to light some false selves of which we may have been unaware.
Since our true self will be sinless, immortal, fully aligned and in harmony with God and Creation, and motivated to engage in creative acts, anything we think we want to do in Heaven that strays from these essentials is likely to emanate from one of our lesser or false selves rather than from our true self.
