Meditation and Reflection
The problem with looking inward is that you see what is in you.
For most people, that is a confusing view. Having fought past their mind telling them that this is stupid, that they’re wasting their time, having fought past a million itches and aches and pains, past the startle reflex at noises and past every other form of distraction, they find a rather muddy (or frightening) reflection.
The meditation shows their inner self accurately: they do not have clarity, so they see the lack of it.
Sometimes, the message is not a cosmic or ancestral affirmation, nor a call to action, nor any sort of external communication. Sometimes, the message is that you are not in a position to hear anything else. You contain confusion, therefore you see confusion.
Conversely, you see something that frightens you, because you contain fear. You see something you desire, because you contain desire.
You do not see what you expected, you see what you are. The message is quite concise, and reflects you.
A lack of clarity is a curable condition, in vodou. If, in your meditations, you are unclear (or angry, or persistently see something that has more to do with what you want than illumination, etc) just know that it does not have to stay that way.
