You should keep in mind that to study with WLP you have to:
- be fluent in Mandarin
- be ready to pay more than $5000 (cost of attending WLP's regular retreat)
- Understand that it will be up to WLP to determine your level of achievement, and he will teach you only based on his assessment of your level, not what you want to study
Regarding certified WLP's senior students - it is good to keep in mind that they will teach only what is approved by WLP himself and based on their personal level of achievement. And this will not necessarily align with your wishes.
