i find it aggravating when people have negative views towards buddhism, asking why do lamas get TB, diabetes etc. the mentality that: if they are so highly-attained why don't they just pray and get better? The ignorance of not understanding and not wanting to learn on this small scale is the same with the DS ban.
From our ordinary perception, we see the Lama falls sick, experiences suffering and helpless just like us but there are many reasons why a Lama manifests sickness :
1) when we willingly do something , no matter how hard, we will not experience suffering or resistance;
example : when a mother delivers a baby and she knows the pains she needs to go through before the baby can be
born thus she "looks forward" to the labour pains because without the contraction pains the baby cannot be delivered.
2) as one of the Lama's skillful means to push the students to a higher level, the Lama willingly ( therefore no suffering is
experienced) absorbs our negative karmas and manifests illness. Hopefully ,this will motivate the students to transform.
3) Our Lama's wish to help us develop compassion or bodhichitta.
We may find it difficult to be genuinely kind to others. However, towards someone from whom we receive love and
care eg. our parents or Guru, this virtuous quality may develop more readily. Therefore the Lama will "sacrifice" his
body for the sake of the students.
4) When a Lama passes away, it can mean either the Lama has accomplished what he wishes to do in this life time or it is
due to the lack of transformation from the students and thus created the cause for them to lose their Lama.
High Lamas can control their deaths and rebirths, controlling their own health is definitely not an issue. We need to look beyond the ordinary appearance to see the intentions of these high Lamas.
