What you’ll need before attempting to solve this puzzle:

• Dendrology technology Level 3
• Puzzles 2, 4 and 9 complete (which you have already completed)
• Soap (Make sure you have extra in case you need to try to achieve “Pure of body” multiple times)
• Fire burning in the fire pit
• A teacher teaching in the school (the more skills the teacher has, the longer the children will stay in the school)

For “Pure of mind”:
- Remove all villagers from the upper-level of the village (between the Tree of Life and the wind flutes) and keep them away while the villager is meditating. You don’t want anyone working on removing debris from the stream nor anyone walking around up there that could possibly disturb the villager you want to meditate. Keep villagers off of the stairs leading up to the wind flutes as well.
- Consider assigning your Builders to Farming or Research temporarily so they will be less likely to choose to clear the debris in the stream while your villager is meditating.
- To keep the children occupied, drop a skilled teacher in the school. All of the children will run to the school, thus not disturb the meditating villager. If the children start to run off, drop the teacher in the school again.
- Drop any adult villager by the wind flutes on the cliff until they start to meditate. The meditation process can last several minutes so be sure to keep all villagers away.
- Once the meditation is complete, you will see yellow sparkles on the villager for a few minutes, indicating that they are pure of mind.
- If the villager gets disturbed and stops meditating, you’ll need to start the meditation process again.

For “Pure of body”:
- Drop the villager who is “pure of mind” on the stack of soap, and they will put one of the bars of soap into the pond to make a nice, soapy bath.
- When the pond is soapy, drop the “pure of mind” villager into the pond, and they will swim around in the sudsy water until they are clean. Do not take them out of the water unless they are “Pure of body.” They may even leave the pond on their own.
- A clean villager will have white sparkles on them for a few minutes.

When the villager is both pure of mind and pure of body, immediately drop them onto the hole in the tree. You will need to have a fire lit at this stage, because the villager will go into the tree, remove the source of the corruption and throw it into the fire to destroy it! It's important not to disturb the villager while they are taking the item to the fire. If you do then the puzzle will not complete and you'll need to start the meditation and soapy bath process over again.

If the villager is unable to enter the tree it means that they are no longer pure of mind and pure of body and you’ll need to start the meditation and soapy bath process over again.

If your villager still won’t meditate, try dropping them by the wind flutes in the very back (there’s a row of 4 right against the mountain, near the cliff).
