Interestingly, the Ganesha pendant is very auspicious and attracts finances. A person bearing it is lucky enough to amass a great fortune and it removes all the hurdles in a person's business and allows them to live a comfortable life.
So therefore, from the point of view of yoga and tantra, Ganesha is always worshiped in the Muladhara Chakra, internally, and externally. He is represented as sitting in yellow color and a square background.
