A favorite Lam Rim study resource at Gaden Choling is the book "The Joyful Path of Good Fortune" by Geshe Kelsang Gyatso (Tharpa Publications, 2nd rev. ed., 1995).
To aid students, we've recast the traditional Buddhist-style outline at the back of the book into the common Western-style outline format. This is still a work in progress, but the material for the outline that's been developed so far, divided into sections by chapter, is given below.
Some places to buy the book are: amazon.ca, indigo.ca, and also possibly at Snow Lion bookstore. (Note: these links are for paperback versions, but hardcover is also available.)
