Lama Ole’s answer:
Most people have some of everything: pride, jealousy, desire, confusion, and anger. Some see something and immediately notice many things they like and maybe one thing they don’t like. These are mostly desire types. Others see right away many things they don’t like and perhaps one thing they like. So these are mostly anger types. And other people are not clear about what they like and don’t like. These are the confusion types.
Some, for example, are desire types at the beginning because they have a physical need for love. Then when the body is content, one’s old anger may come up and start to find a lot of faults in one’s partner. We actually see this often—a beautiful honeymoon and then afterwards the people yell at each other.
I myself am purely a desire type. My mind works in such a way that I understand others’ mistakes as wrong programs that are being thrown out. I forget almost all the mistakes. And when we meet the next time, I greet you happily because I have forgotten past problems. But if someone has done something good, then afterwards I remember very well and I like to ask about the experiences.
There are anger types who criticize everything. However, since they know exactly what they don’t like, they hold on to it less than other people might. This is how they make fast progress. I know such a woman; she had astonishing progress with her meditation. Anger types have to learn from situations where they always get angry or think that they have to protect themselves. They need a protected frame where they are not attacked and can thus let go of their defensive attitude. They need space around them in order to see how things really are and how beautiful the world is in its true nature. Then they discover their richness and can let their whole strength, love, and surplus play freely. Most anger types end up with the Nyingmapas; their teachings are directed towards that.
Desire types like everything. Instead of moving ahead in a focused and linear way, they jump fully into things and make progress like this. Desire types have to learn to recognize the difference between impermanent and permanent things. They mostly end up being Kagyu.
The confusion type often has to take the way of thinking. He progresses step by step through increasingly better understanding and clearer insight, level by level. Most confusion types end up with the Gelugpas.
The different schools function more or less in the following way. For the Nyingmapas, the view from above is most important: by flying across a lake, for example, to get an overview of it, one gains an understanding of the lake. With the Kagyupas, the direct experience is most important: one jumps into the lake and swims, feeling the water on the body. For the Kagyupas, everything is very close like in a family. And for the Gelugpas, analysis and understanding are essential: the approach is to take a sample of the lake water into the laboratory to see what’s inside.
We cannot say that one approach is good and another bad. One school is good for some and another school is good for others. If one follows the right path, one will reach the goal. And when one has become a Buddha, then the difference is gone as to which path one took. It is only a question of how to go up; when one has arrived, there is no difference anymore.
