This is a special practice of relying upon our Spiritual Guide as a Buddha and making praises and requests to him, but it also contains beautiful essential instructions on all the stages of the path to enlightenment and training the mind, as well as both the generation and completion stages of Highest Yoga Tantra.
We also make specific prayers for our friends, family members, Sangha and others who are suffering or who have died. This practice includes a vegetarian tsog offering, which you can bring with you to puja or simply imagine.
