36. That one shouldn't study and practice the Tibetan traditions without a teacher.
"Question: Do we need a guru to get enlightened or is it sufficient just to study Dharma, live a moral life, attend teachings and practice meditation?
His Holiness The Dalai Lama: Of course it is possible to practice, study and lead a moral life without actually seeking a guru. However, you must understand that when you talk about enlightenment, you are not talking about something that can be attained within the next few years but about a spiritual aspiration that may, in some cases, take many lifetimes and eons. If you do not find a qualified teacher to whom you can entrust your spiritual well-being then, of course, it is more effective to entrust yourself to the actual Dharma teachings and practice on that basis."
