I was recenty very surprised,
when I found -which I definitely consider to be mistake- that in the book "Words of My Perfect Teacher"
published recently in my country, there was mistake in the mandala of yab/yum-Vajrasattvas of five families.
I know that details of practices are not to be discussed here;
still, we have a PUBLICLY AVAILABLE text (an important one, I think)
and there is mistake that seems obvious to a ´seasoned´ practitioner
but may be quite misleading for a beginner
who wants to make his/her ngöndro
before having more knowledge about five buddha-families.
(I really think that consequencies may be quite heavy -
- at very least, people who discover the mistake only later
may (after accomplishing many mantras in a mistaken way) feel really insecure.)
(So I am using this Ekajati-day to point-out the mistake to perhaps find some more-less solution.)
