Tibetan Dream Yoga Character Visualisation

Hi, I’ve been reading “Dream Yoga and the Practice of Natural Light”
by Namkhai Norbu, Namkhai Norbu Rinpoche, Michael Katz and one of the instructions in the book is to visualise a glyph or Tibetan character as one falls asleep. The trouble is, I want to print it out in a large size so that I can visualise it easier. There’s an example of the character right at the bottom of this file – http://www.plotinus.com/zhine_tibetan_dream_yoga_part2.htm
it’s on the left hand side, next to .A

Could anyone please point me to a bigger example of this character on the web, please?

Thanks,
Tom
