Urmila devi dasi: Please accept my obeisances. All glories to Srila Prabhupada!
At this link: http://illuminationeducation.com/freebooks on the bottom of the page, you can find our Illustrated Bhagavad-gita. It is designed for teaching anyone age five and up. It is a free download, with all encouragement to copy, print, and distribute as you like.
The file takes a while to download because in the book are links to audio for each verse. You can also download the audio separately, with the links at the bottom of the URL page.
Your servant, Urmila devi dasi
