Lama Ole’s answer:
There are methods on the general level and on the highest level. On the highest level, there are the methods of identification through the three types of tantras.
The desire type meditates on the mother tantras. Here, the building-up phase is short and the completion phase long. One doesn’t pay too much attention to all the details but just sits there and feels really great.
Angry people keep the completion phase short because it feels too personal. This type of person sets a high value on having everything fit in its place, and he would rather keep a bit of distance. And for the confused people, both phases are almost equally long. They can also use the many details in the meditation to help them stay focused.
Karmapa is the activity of all buddhas; therefore, in the meditation you yourselves will notice which situation you are in. If you are desire types, it is not so important what the crown means or what Karmapa knows or can do. The main thing is the good feeling during the melting phase. If you are an anger type, you’ll want to know what every detail means and the melting phase doesn’t need to be so close. If you are a confusion type, then the emphasis goes back and forth. Those are the three ways to work with the meditation.
