I think H would not be so politically incorrect as to put Gandhi, a Hindu, next to cowhide which is the skin of a Hindu sacred animal.
Since my ancestors are from India I hope you will not mind if 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.
