What Khensur Rinpoche talk about is:
'the big problem here is that there is not one single Buddhist scripture which has mentioned about the Buddha having left relics of saliva / blood or brains.'
Not saying that no relic ever exist. So you are mixing up the two.
Rinpoche explain as below(
http://www.casotac.com/CASonline%20Articles/23122009_2.html):
'When Lord Buddha manifested Nirvana at Kushinagara, it is recorded in the scriptures that the bone relics of Lord Buddha were devotedly collected by the gods to be enshrined and offered devoted services in their heavens. Venerable Ananda and Venerable Kashyapa requested the gods to leave some relics in our human realm as a source of merit and blessings for our world. As a result, some of the Buddha's bone relics remained with us and subsequently, it is recorded, too, that Nagarjuna enshrined some precious relics in treasure casket at Bodhigaya.
However, the claims by this association, of the sudden but un-accounted for revelation of thousands of blood, brain or saliva relics, could not be referenced from any of the holy scriptures, history, tradition or in the Tibetan circle. '
This Kadhampa Buddhist Association arrange regular relics tour in Asia, with thousanads of relics. CAS Online mentioned that kind of 'magic' show in TV:
'The Taiwanese "tulku", the alleged incarnation of Chenrezig, has also, in front of television audiences, held an alleged hair of Lord Buddha between his fingers, with the hair apparently twitching like a worm from side to side in his hands. When he dumped the hair in a mug of liquid, the hair apparently "swam" of its own efforts, '
It is said that $ trading is involved behind it.
See one of their advertisment as enclosed.
Khensur Rinpoche also mentioned :
'There has never been any historical precedent or valid scriptural basis for wearing these green-striped robes. In fact, I am concerned that their lineage is not authentic because "Serkong Tritul", head of this association, has flipped-flopped by declaring himself to be the reincarnation of this, and then, that, different Ganden Tripas in the past. In addition, he has switched his claim before to having been the reincarnation of a great yogi practitioner "Apong". It appears that there has been some contradictions in his own claims !!
Let me recount, in short, how reincarnation became institutionalised in Tibet. The first recognised reincarnated master of Tibet is the first Gyalwa Karmapa. Subsequently, the recognition of reincarnation of past masters ( called "tulkus" ) spread to the other traditions. In the Gelugpa lineage, it is mainly the Dalai Lama or the Ganden Tripas who will recognise Tulkus. In the Sakya lineage, the Sakya Trizin will be mainly responsible while for the Nyingma lineage, great masters such as the Mindroling Trichen, the late Dudjom Rinpoche or Palyul Penor Rinpoche will be the authority. In the Drikung Kagyu, the Drukpa Kagyu and other lineages, the respective great masters will fulfill the task and they each have their respective, stringent and definitely valid systems of recognising incarnations of great masters from their lineage.
Here, "Serkong Tritul" is not recognised by any of the senior lineage-holders of any of the schools. His Holiness the Dalai Lama has never recognised him as a Tulku and neither has any of the heads of the other lineages. This association claims to represent the Kadampa lineage, but all the old Kadampa masters have passed away, so these old, holy Kadampa masters could not have recognised them as Kadampas or as tulkus of the Kadampa lineage.
The formal inheritors of the Kadampa lineage are the Gelugpas. None of the Gelugpa lineage-holders alive today - not His Holiness or the Ganden Tripa - recognised him as a tulku. So, merely claiming himself to be a tulku does not and could not, at all, factually make him one.
They have been requested to offer proofs of their recognition as Kadampas. "Serkong Tritul" has also been questioned many times to provide proof of who recognised him as the real tulku of Serkong Tritul and to date, they could not offer any answers or proof.'
Trinley Kalsang mentioned some frequent quoted POV in this forum which looks strange. I would like to add one more:
- Those claim themselves practicing DS must be right in all aspects, those not practising it must be wrong in all aspects
So it is kind of ''X don't practice DS-> X is not worth listening to, no matter what it is about(those not related to DS). Y practice DS-> Y must be non-questionable in his discipline, his activities etc..'
Chairman Mao once said 'enemy's enemy is our friend'. It is a right tactic politically, but for religious matter this may not be a good idea.
BTW, this Kadhampa Buddhist Association has announced no further relationship with DS openly. How come they come back now?
I don't want this forum be a sub-firum of Kadhampa Buddhist Association. I put it straight: this Kadhampa Buddhist Association organization is not appreciated by the Chinese-speaking Gelukpa community, no matter they practice or not practice DS.
