Clairvoyance is indeed latent and capable of being developed prematurely of its generally evolutionary appearance and development if the price is paid for this premature development.

Other names have given rise to its manifesting,namely the marking of this phenomenon on different levels, such as dreams, prophecy,etc.

Clairvoyance is a tool to be used as research into the past. We hear of different forms of this in the Cayce readings of the Akashic records as well. Amid constant interruption of an encroaching world, this research is impossible and the idea of the retreat is in order, and necessary for this and any associated sorting out of "mystical experience."

They know that it is a power latent in all men, and that it can be developed by any one who is able and willing to pay the price demanded for its forcing, ahead of the general evolution.

The notion of occult hierarchy was postulated at the research at Adyar since the 1910 inception date: Note the quote below:

The broad Theosophical outline of evolution has been followed, and it is
given among the “preliminaries” in Chapter I. This governs the whole, and is
the
ground-plan of the book. The fact of an Occult Hierarchy, which guides
and
shapes evolution, is throughout taken for granted, and some of its
members
inevitably appear in the course of the story. In order to throw
ourselves back
into the earliest stages, we sought for our own
consciousnesses, present there,
and easier to start from than anything else,
since no others were recognisable.
They gave us, as it were, a footing in
the first and second Chains. From the
latter part of the third Chain and
onwards, we traced humanity' s story by
following a group of individuals,
except where this group was otherwise occupied
during any important stage of
evolution-- as in the beginnings of the third and
fourth sub-races of the
fifth Root-Race; when that was the case we left it, and
followed the main
stream of progress. In this record comparatively few details
as to persons
can be given, the sweep of the story being so large. Many detailed
lives,
however, have been published in 'The Theosophist, under the general title
“Rents in the Veil of Time”-- rents through which glimpses of the past of
individuals may be seen. A volume of these, named Lives of Alcyone, will, we
hope, one day be published, and to that will be appended full genealogical
tables, showing the relationships in each life of all the characters so far
identified. Work of this kind might be done ad libitum, if there were people
to
do it

Individuals retain their individuality but reappear under different disguises and names through out succeeding ages . This recurrence is postulated under the teachings of reincarnation and in Judaism is frequently experienced with writing afterward of it in the writings of Isaac Luria (the Ari) through his scribe/transcriber and called "soul attachment" and is the way for a soul to grow over an expanse of the aeons in the search for an evolving to perfection.

The link provides a table of the names of the masters and their appearances in their manifestations. They have grown to be the Masters as they now stand. Isaac Luria though not named was one such.

SURYA ...
The Lord Maitreya, the present Bodhisattva, the Supreme Teacher of
the world

MAHAGURU ...
The Bodhisattva of the time, appearing as Vyasa, Thoth
(Hermes), Zarathushtra, Orpheus, finally as Gautama; who became the Lord Buddha

BRIHASPATI ...
Now the Master Jesus.

VENUS ...
Now the Master Ragozci (or Rakovzky), the `Hungarian Adept,' the Comte de S. Germain of the eighteenth century

We read on the plane of history of Jesus (possibly in India at one time?)
and of St Germain. More of that later.
