One must avoid false tertons who are reincarnated long term enemies of Padmasambhava and Yeshe Tsogyal who:1-
Tell some people they are not tertons. But tell others they are tertons as we see by themselves openly as well as their aides.2-
Make up funny combination deities and fake tantric figures corrupting vajrayana as prophesied by Padmasambhava for the degenerate age by the worst spirits around.3-
Who break samaya with great gurus that they use for publicity and fund raising in order to buy property in various continents for themselves.4-
Who were banished by those dead gurus that initially hoped to correct them, that now they use for publicity, who told them to stop their teachings and false claims before being banished.5-
Who make up fake lineages that no lama or academic accepts as real.
As the Tulku Thondup's passage shows, major fake tertons do not make up their terma. It is channeled by demonic beings who are the major enemies of Guru Rinpoche. Anyone following such figures should know the secret dimensions of these matters are great disasters that will affect one through many lifetimes. The outer dimensions of great power and great money as signs of importance/danger/concern are only definitive values for worldly persons, not the essence of great malevolent beings most of whose types are not outwardly visible to humans. Any reassurance or appeasement by those who have made tragic positive karmic connections and/or intentional aspirations towards fake tertons' mandalas should be regarded as dangerous naive advice. Sanitizing the following of a fake terton, enemy of Guru Rinpoche, as admitted shows imbalance and should be dismissed.
Vajrayana is not for everyone. These invented fake tantric figures, deities, terma, practices and lineages is how Vajrayana was prophesied to be attacked and degenerated. Vajrayana states one should deeply investigate a teacher before committing. Ignore reassurances that oppose such Vajrayana tenets, lineages, valid deities, etc. as they are not your friends but only leading one to the abyss of many lifetimes' downfalls and unnecessary great suffering. Investigate through the families of any dead guru being used for publicity about banishment of fake tertons. There are many valid lamas to follow and the best way to salvation from fake tertons' ever expanding webs is through genuine gurus and ultimately Guru Rinpoche himself.
"False Termas: Reverse Effect of Practice of Some Termas:
The reason contrary and inauspicious results occur when
some Termas are practiced is that there are false discovered
teachings. In particular there are false texts that look like
Terma script, and which are by false Tertons, the rebirths of
wrongly aspiring evil ministers (*) of the ancient time who
have the support of certain demonic spirits as the protectors
of those Termas. Such teachings belong to demonic forces.
By reciting and practicing those false teachings the follower
will move only in the wrong direction.
(* Evil ministers, Dud Ion (bDud Blott): While Guru
Padmasambhava was establishing Buddhism in Tibet until it
reached its peak, many esoteric teachings were concealed
for the future. Powerful but wrongly inspired
ministers, people and spirits made evil aspirations to
corrupt the Terma teachings by discovering false Termas
in the future. That is why false Termas are discovered in
Tibet from time to time as counterparts to the positively
effective and precious Termas.)...
THE REASON WHY NEGATIVE ASPIRATIONS WERE
MADE BY EVIL MINISTERS, ETC.:
Negative aspirations were made by evil ministers in order
to obstruct the enlightened activities of Guru Rinpoche. If
disciples of the profound Termas of Guru Rinpoche who
have the desire to achieve supreme attainment are fooled
into mistaking these false teachings for pure teachings, and
if they practice them, it will cause the decline of their
fortunes, their life, and so on. If any short-sighted people
who have no desire to attain a perpetual goal (enlightenment)
should practice these false teachings, then for the
time being it might seem to be helpful for increasing life,
majesty and the power of speech, but (eventually) those
teachings will become a cause of samsara and hell for them."

Dzogchen masters I know say: 1)Buddhist religion essence is Dzogchen 2)Religions are positive by intent/fruit 3)Any method's OK unless: breaking Dzogchen vows, mixed as syncretic (Milanese Soup) 4)Don't join mandalas of opponents of Dalai Lama/Padmasambhava: False Deity inventors by encouraging victims 5)Don't debate Ati with others 6)Don't discuss Ati practices online 7) A master told his old disciple: no one's to discuss his teaching with some others on a former forum nor mention him. Publicity's OK, questions are asked from masters/set teachers in person/email/non-public forums~Best wishes
