Dear Poonlarp
Yes, perhaps this person thought he deserved it.
It is not the gifts, praise, etc which made this person have negative thoughts. We all have negative thoughts, arising from delusion/ignorance and reinforced by its two best friends which are anger and attachment. As we know, these are the three poisons which have kept us imprisoned in samsara.
So we are imprisoned to the point that even if we are given the teachings to liberate ourselves, we are not able to apply because we don't even know the right way to start LEARNING the Dharma. Thus, the compassionate masters such as H.H Pabongka Rinpoche taught us through the Lamrim how to learn the Dharma even before he gave actual teachings on the Dharma itself.
Your friend has the good merits to meet and be a close student to a Rinpoche. However, just like all of us, we fall into what is illustrated as the Three Pots :
1. The Upside - down pot
2. The smelly pot
3. The leaky pot
We may be near and study under a most qualified Guru, but unfortunately we got a POT PROBLEM. Example. our minds are closed, deluded and forgetful. How could our negative views be changed if our mind is similar to one of these pots.
This quote reminds me of the purpose of studying and learning :
Owing to your study, you understand Dharma;
Owing to your study, you stop sinning;
Owing to your study, you abandon the meaningless;
Owing to your study, you achieve nirvana.
- Sayings of the Buddha
The guru can use the 4 ways of gathering disciples and all the skillful methods of a mahasiddha, but it is still up to the student to stop sinning, to abandon the meaningless etc...
The Great Pabongka Rinpoche taught in the Lamrim as follows :
While the Dharma student listen, six things should be present:
- the right time
- deference
- respect
- lack of anger
- the intention to put the teaching into practice later
- an absence of arguing with the teaching
The explanation then for what happened to your friend is though he had the opportunity to be close to a Guru, the 6 things were NOT present in him as a student. Perhaps what was present were the 8 worldly concerns and a grand party organized by the Snakes, Roosters and Pigs.
May Protector help us always so that we do not experience such negative fate and fall of the path to ultimate liberation.
