You need to move 10 tiles in one direction to meditate again when you get this message. Note that you can still join a path after meditating even if you receive this message, so it can be safely ignored if you aren't looking for skill.
*This is indeed a special place.
You have found a special tile that belongs to a path.(no message on special tiles of the path of insanity)
*You decide to start pursuing the insights of the path of knowledge
Message you get if you choose yes in a path dialog (see above)
*You still need to let your progress sink in for several hours/ days / more than a week
After meditating again on a special tile (after choosing path dialog) you get this message on top of the recent meditation message.
*You gain no inspiration here for your own path.
If you meditate on a special tile that is on a path other than the one you will have chosen you will receive this message.
*You should return here when you have become better at meditating.
You have found a "special tile" but do not have the required skill to start a path.
