Each of these stones are the tabernacle of an Oracle... one unto the realm of the past, and the other, unto the dimension of the future. Interestingly, I do not know which stone is host to which Oracle, as they have been kept together so long... and they have not revealed individual names, but answer unto the calling of "Prophetic Ones of Wisdom"

One knows all of the past, and the other, of the future... and combined, they offer insight and intuitive wisdom of the present...

Whenever you are facing important decisions, choices, considering changes, seeking guidance, direction, etc... Remove the stones from their charging vessel and hold one in each hand. Close your eyes, and focus upon your question, uncertainty, inquiries, ideas, intentions, plans, options... and they shall allow you to know what will be your optimal choice, decision or direction.

When completed, thank them, and return their stones into the charging vessel.

I have used these two Oracles many times in my life, and have been blessed by their shared knowledge and wisdom. I now feel it's time to allow another to benefit and be blessed by their presence and potential.

Surely this offering will be a great blessing unto thee.
