Crystals for Boundaries
Black tourmaline, obsidian and hematite are the three stones traditionally kept for boundaries. The set is deliberately heavy and dark, because a boundary is not a gentle thing: it is a line you hold when someone leans on it. A stone in the pocket is a cue to say the short sentence instead of the long apologetic one.
The six
Which six stones does tradition name for this?
Six, not sixty. Each one carries a different reason, so you can pick the reason that sounds like your week rather than buying the whole row.
Black Tourmaline
The standard boundary stone in modern practice. It is kept for the relationships where you already know the answer is no and keep producing reasons instead.
Obsidian
The mirror stone, used for the uncomfortable half of this work: seeing what you get out of being endlessly available to people who do not reciprocate.
Hematite
Heavy for its size, which is the entire argument. A boundary needs weight behind it, and a dense object in the hand is a small physical rehearsal of that.
Tiger's Eye
The nerve stone. Most boundaries fail at the moment of speaking rather than the moment of deciding, and this one is kept for the speaking.
Labradorite
Traditionally read as keeping your own energy your own. It suits people who come home from every gathering feeling emptied out and cannot say why.
Amazonite
The kindest stone here, and the corrective. Boundaries do not require coldness, and this one stands for saying no plainly while staying warm about it.
The practice
How do you work with the set?
Write the sentence you need to say, in under ten words, and keep the stone on top of it.
Practise the sentence out loud until it stops feeling rude.
Carry the stone on the day you say it.
Afterwards, notice that the person survived, which is the evidence you will need next time.
Read here as a language of symbols. Medical, legal and financial questions belong with a professional.
Questions
What else do people ask about this?
Do I have to explain my boundary?
No, and long explanations usually invite negotiation. A short sentence with no reasons attached is harder to argue with than a paragraph, because a paragraph offers several places to push. No is a complete answer on its own.
What if holding a boundary feels cruel?
That feeling is common and it is not evidence. People who have been accommodating for years usually feel harsh at the exact moment they become reasonable. Check whether anyone was actually harmed or whether someone was merely inconvenienced.

A need is one door in, a stone is another.
Six names, and behind each one the tradition that gave it the job and the plain limit of what it cannot do. The body reads the same set differently, and the seven centres are that reading.
- 104
- stones, each with what tradition says
- 64
- everyday uses, six stones under each
- 7
- centres, the same set read through the body
