Ganeshji symbolises the consciousness which is omnipresent.
Ganeshji is not somewhere outside of us, but the very centre of our life.
Not everybody can perceive the formless without the form.
Our ancient Rishis knew this; so they created the form for the benefit and understanding of people at all levels.
Therefore, install the idol, worship it with infinite love,
meditate and experience Lord Ganesha from within
