Don't be thinking that this lama over there is giving better teachings or that this lama over here is giving more secret initiations. Leave that. Just keep the practice very simple, try to stay in the moment and try to stay mindful.
Even if the hermits do not appear to benefit other beings with their presence or teachings, still they are enormously inspiring to many. Perhaps, in this lifetime, they were meant to work on their own practice, to try to purify their own mindstream so that in future lifetimes (that will last a lot longer than this one), they will be fit vessels to give the teachings to others.
Doing retreats, getting personal teachings from time to time from inspiring teachers, all of this helps to recharge our batteries. Then we get inspired and can carry what we've gained into our daily life, which is very important.
The Tibetans have many teachings on how to die, consciously, and how to remain in the clear light, and it works. You can see it working, and they can stay in that state for hours, days, or weeks.
Traditionally, women didn't have much a role in Buddhism. The books were all written by monks, for other monks. So the general view of the feminine was rather misogynistic, with women playing the role of the forbidden other, waiting to pounce on innocent little monks! In that society, it was hard for women to become educated and get the deeper teachings and really become accomplished.
I know many Catholic priests and nuns who use the Buddhist teachings to become better Catholics, and Jews who use them to become better Jews. Why not?! It just takes us towards more deeply recognizing our original nature, which is what we all share after all.
I think it would help if, when people are first ordained, they underwent a period of strict training, maybe for several years. During this time they would learn basic Buddhist philosophy in a monastic community where all the teaching and training was directed toward living a perfect monastic life and wasn't channeled out to fit into the lay life - which is what usually happens in Dharma centers where the teachings are directed toward how to live the Dharma in your everyday life.
