in my own life and spirituality, I'm constantly invoking Ganesha -- before every meditation, every healing, every process, concert, whatever. this is part of the Indian tradition, and part of the meditation/spiritual life that I learned in India...
so I'm constantly thinking about, saying a mantra to, or singing about Ganesha. it's common, in the Indian tradition, to be doing that.
I also keep Ganesh statues or images of some kind at every doorway in my home and also down one walkway, before people reach the entry door -- he automatically washes out negativity from people coming into the house and gives them a beautiful blessing.
it's a smart mechanism, to have Ganesha greet people before they enter your home -- in India, if you visit a temple complex, you'll see a Ganesh temple in front of the main temple buildings. people ALWAYS go first to Ganesha, then into the other deities.
