Does anyone know where it is possible to identify a lama incarnation? Hi I'm just seeking advice if it is possible to identify a Lama incarnation, whom to speak to etc.
In Tibetan Buddhism, the procedure is AFAIK only documented for Tulku (high-ranking Lamas):

When an old tulku dies, a committee of senior lamas convenes to find
the young reincarnation. The group may employ a number of methods in
their search. First, they will probably look for a letter left behind
by the departed tulku indicating where he intends to be born again.
They will ask the close friends of the departed to recall everything
he said during his last days, in case he may have given hints. Often,
an oracle is consulted. Sometimes a prominent lama has a dream that
reveals details of the child's house, parents, or of geographical
features near his home. Sometimes heaven presents a sign, perhaps a
rainbow, leading the search party to the child.
