Ganja !

[Alam Shah]

Let's refresh ourselves and go back to basics, shall we.

What is a ganja?
From Bambang's Ensiklopedi Keris...
Ganja is the bottom-most area of the keris forming the base. At the centre of the ganja is a hole for the "pesi" (tang) portion. The blade and the ganja forms a union that cannot be seperated.
Many cultural aspect indicated that it is a symbolic union of lingga and yoni.
The ganja represents yoni while the blade with it's pesi represents lingga.
In ancient culture, the union of lingga and yoni represents fertility, eternity and power.

Perhaps, a design element that form part of the physical and also magical aspect of the weapon, with its multiple symbolism, rituals and construction element.
Note: Earlier talismanic blades (sajen) does not seem to have this feature.

I guess, initially it might be (and very well still is). But as time goes by, with influence from a few different religions, the keris evolves and the meaning of might have changed through time.

Personally, I think so but I cannot prove it but if you look at blades through the ages, you'll see quite a lot of evolution and styles.

Hmmm... perhaps? Personally, I guess not, but to enpower the blade, perhaps? Open for discussion...

This, I think Michael has my sentiments as well. "I don't think anyone of us can prove the reason for the ganja being there".
