[Cofeeman]

Each of the Buddhist Traditions has a bit of a different method for newcommers who wish to follow the Dharma Teachings. Some people, myself included, took a formal Refuge vow with my Lama after having attended Teachings for a time and made a choice to commit.

However that is certainly not the only way to go. Mostly to me it has to do with the intent to embrace a different way of life The Formal Vows were good for me to help set myself while other people might find that to constraining.

my advice would be to check out each of the schools and see which is the best fit for you before making a final choice.

All the Best
