Wow! Thank you for sharing!
I was always told that, if we have strong faith and trust in our Guru, the most precious image and mantra is our Guru's mantra. And I think that is very logical, because our Gurus are Vajradhara, he is a real Buddha that sits before us and teach us the Dharma. I wish I have the good fortune serve a Guru 24/7 rather than just sit infront of a statue to meditate lol! For those that serve the Guru closely, I envy you hahahaha.
