…when it has not yet been acted on.
Vision, by its very nature, has a ethereal, foggy, transient quality.
You only notice details by constant and continuous observation. Most “visions” can be elusive and unclear simply because we do not have or take the time to observe them long enough to notice all the details. Dreams in the night are bounded by the hours of sleep. Visions in the day – waking visions, daydreams – are brief and illusory, shattered by sensory input and kind people asking us if we’re all right or what we’re thinking.
When visions are gone – however clear, however divine – they can be forgotten within minutes or hours. Their clarity recedes, their meaning is unknown, they are discarded.
The only way to strengthen vision is to record it and then observe it in the mind’s eye, recall it, remember it, seek clarification, and most importantly act on it.
If it’s not recorded, it will be lost. If it’s not acted on, it is voted an unimportant, wispy product of the mind’s emotion, and discarded with the dendritius of daily forgettings.
