Apparently, in the Buddha's final moments, his disciples asked:
Who will guide us once you are gone?"
“ APPA DIPO BHAVA — Be a light unto yourself.”
During a recent dark night passage in my life, I was asked, "Do you see the light at the end of the tunnel?"
I paused and these words came out of my mouth:
"Actually, I see that the light guiding me through the tunnel has been within me...all along."
It is in all of us.
