Pinas are only recommended for those who have already gained experience first with Moquis, then with Bojis, because of their power.
Originally from Kansas
Each of these stones exhibits a different polarity depending on the type of surface:
The roughest one, called Osiris, is of masculine polarity (Yang principle).
The smoothest one, Isis, is of feminine polarity (Yin principle).
These stones should be used together, one in each hand, to recenter the subtle bodies and balance the polarities of the physical body. Furthermore, the pair Isis and Osiris facilitate astral travel. When using them, one should also ground oneself with a large tourmaline or black obsidian (even better, rainbow obsidian for astral travel), and allow the energy to flow for 15 to 20 minutes, no longer.
These are very powerful stones for balancing and recentering Yin and Yang. They recharge all the meridians of the physical body and the subtle bodies, eliminate blockages (by placing them on either side of the area to be treated), close the aura (except in cases of large tears such as after surgery or an accident), and provide excellent protection.
Beyond 20 minutes, they can facilitate an out-of-body experience. It's essential to immediately release the stones to return to your body. They are also very useful for inducing deep relaxation and significantly boosting energy flow, excellent for cases of anemia and hypotension. Piña stones can quickly restore excellent memory with daily use; they can also be placed on your desk for intellectual stimulation, mental clarity, and concentration.
Primarily composed of iron and sandstone (the Pinas are covered with pyrite), this sacred stone, according to an ancient legend, was used in a ritual to receive messages from beings on other planes, mainly from deceased relatives, to let them know they were in the afterlife.
