Well it's important for me to know since my point is to find out whether someone who has received Rinchen Terdzod but not Dudjom Tersar (explicitly) can practise or transmit Dudjom Tersar. A Lama said he is not sure but maybe when DKR or Dudjom Rinpoche might have included it when they 'edited' Rinchen Terdzod? (don't mean to add more rumor and confusion, but the Lama himself was not sure so take this with a pinch of salt) So hope someone else can have more insight?
Dudjom Tersar is not in Rinchen Terzo. A person who has not received Dudjom Tersar cannot practice or transmit it.
