Just because he's bitter and disillusioned because he prefers to cling on to his ego than to let it go, does not mean that what he says is right. He is merely spouting his own opinions and bitter opinions about things and conditions. To me, it is not relevant at all to any other Buddhist practitioners because it is just his opinions! Who cares about the opinions of an unenlightened person who is not even a monk about Buddhism? What is he trying to prove? Nothing.
When people see their Gurus, it reminds them of their good qualities but when this guy look at his Gurus, he allows his insecurity to take over…to see his Gurus as not perfect even though it is stated in countless sutras and tantra that the Guru will exhibit human-like tendencies such as displaying "mistakes" to teach the disciples a lesson and educate them, and not appear to be too far away for the disciple to achieve.
It is really about time that someone kind of alert the Buddhist world about such things to clear up misconceptions, especially on the topic of Guru Devotion. It is the most powerful method to transforming the mind, and thus it will be prone to many misunderstandings as the mind does not want to be retrained, naturally, and the mind will always find excuses to slink away from it and not hold Guru Devotion.
With his quagmire of wrong views, again, for people who knows more Dharma knowledge, it is obvious that Schettini knows very little in Tibetan Buddhism, and in that sense, Buddhism as a whole and thus is not credible as a scholar in Buddhism in any sense. Because we do not need another persons' opinion on the Dharma. We can already form our own erroneous opinions without his help.
