Cadena Thoughts...

I offer some (more PC and also relevant to India) suggestions than have been offered previously.

1. The conch shell:
A symbol of knowledge, power and glory

2. The Wheel
The wheel symbolizes infinity and knowledge. Also has a place on the Indian flag.

3. The Lotus Flower
A representation of spirit and harmony, and an elegant environment.

4. The Chalice
A representation of riches, desires fulfilled and luxury.

merika, you are right. 2008 cadena is indeed one of these. ;)
