This serial includes the story of the hermit mentor on Gallifrey.
[This is based on the story of Buddha's silent transmission of the
Dharma to Maha-Kashapa]. Here is a transcription:
JO: It makes it seem sort of pointless, really, doesn't it?
DOCTOR: I felt like that once when I was young. It was the blackest
day of my life.
DOCTOR: Ah, well, that's another story. I'll tell you about it one
day. The point is, that day was not only my blackest, it was also
JO: Hmm? Well, what do you mean?
DOCTOR: Well, when I was a little boy, I used to live in a house
that was perched half way up the top of a mountain. And behind our
house, there sat under a tree an old man -- a hermit -- a monk. He
lived under this tree for half his lifetime, so they said, and he
learnt the secret of life. So, when my black day came, I went and
asked hom to help me.
JO: And he told you the secret? Well, what was it?
DOCTOR: Well, I'm comming to that, Jo, in my own time. Ah, I'll
never forget what it was like up there. All bleak and cold it was --
a few bare rocks with some weeds sprouting from them, and some
pathetic little patches of sludgy snow. Yes, it was just gray --
gray, gray, gray. Well, the tree the old man sat under was ancient
and twisted, and the old man himself was... he was as brittle and
dry as a leaf in the autumn.
JO: Well, what did he say?
DOCTOR: Nothing, not a word. He just sat there silently,
expressionless, and he listened whilst I poured out my troubles to
him. I was too unhappy even for tears, I remember. And when I'd
finished he lifted a skeletal hand and he pointed. Do you know
what he pointed at?
DOCTOR: A flower -- one of those little weeds. Just like a daisy it
was. Well, I looked at it for a moment, and suddenly I saw it through
his eyes. It was simply glowing with life, like a perfectly cut
jewel. And the colours -- well, the colours were deeper and richer
than anything you could possibly imagine. Yes, that was the daisiest
daisy I'd ever seen.
JO: An that was the secret of life -- a daisy? Hmm. Honestly Doctor.
DOCTOR: Oh yes, I laughed too when I first heard it. So later, I got
up, and I ran down that mountain, and I found that the rocks weren't
gray at all. Well, they were red, brown, purple and gold. And those
pathetic little patches of sludgy snow -- they were shinning white --
shinning white in the sunlight. You still frightened, Jo?
JO: No, not as much as I was.
DOCTOR: That's good.
