carnelianThe Agni Purāṇa recommends thirty-six gemstones for activation of rājayoga for the kings. I guess ordinary mortals can also make good use of these recommendations. The Sanskrit recommendation and our translation is given below.

Vaidūrya Correction

Normally Used but Wrong gemstone. This is not Vaidurya

Normally Used but Wrong gemstone. This is not Vaidurya

It is very interesting to note that ‘vaidūrya’ which was suspected to be cat’s eye gemstone by astrologers for such a long time seems to be quite different. Vedavyāsa specifically uses the word ‘nīla-rakta’ indicating that it is bluish-red in colour. Cat’s-Eye is a feature that can apply to many gemstones including Cat’s Eye Apatite, Cat’s Eye Aquamarine, Cat’s Eye Diaspore, Cat’s Eye Scapolite, Cat’s Eye Tourmaline. Cat’s-Eye simply means a line of light that tilts with the stone. Don’t get carried away with that. What we are looking for is a gemstone which has the blue and red colours blended together.

Application

These thirty-six gemstones are recommended based on the 36 drekkāṇa. For many thousand years the Indians, Persians and the Egyptians have used the drekkāṇa for timing political events and it is evident that this recommendation could be on these lines.
