THE CEREMONY OF MINERVAL AND FIRST DEGREE

[Note: Crowley wrote this essay before he made the 
final revisions to the I° ritual. The I° portion of 
this essay included a discussion of Masonic symbols 
which do not occur in the current version of the I° 
ritual. The I° portion of this essay has, 
therefore, been edited to conform to the symbolism 
used in the current version of the I° ritual. The 
edited material is given in square brackets. The 
original essay is preserved in the O.T.O.

Minerval
The Ceremony of Minerval, in appearance trivial and 
formal, contains a doctrine of substantial occult 
significance. The Candidate before admission is 
bound by an obligation in which he recognizes 
Baphomet as the Supreme Authority. This represents 
the free choice of a free will to submit itself to 
the magical formula represented by Baphomet. The 
Candidate is seized, blindfolded and bound head and 
foot. This represents the first operation of this 
formula. The soul is drawn within the planetary 
current and its sight and freedom of action are 
immediately taken from it.
He is described as a native of Corinth, and as 
having attained the freedom of two cities, Athens 
and Mitylene: the initials of these cities K A M 
giving the Sanscrit word for "work" from which 
Karma or Kamma is derived. They add also to the 
number 61, a prime number whose 6 and 1 suggest the 
hexagram, the symbol of the Sun, which is often 
represented by a six rayed star with a yod in the 
middle. 61 also represents the word for 
"nonexistent," for "towards" and for "I myself." 
Read in conjunction these words explain the 
formulation of the negative in the ego. 61 also 
represents the Hebrew word for "womb" and that for 
a "little habitation." There is another and even 
more important explanation of these words which is 
however unsuited for members of any grade below the 
Sixth.
The Candidate sees that he is travelling to the 
City of the Sun, which again repeats the solar 
symbol and gives the name of another city. The 
adding of this H raises the number to 66, which is 
the number of the Great Work, and is the sum of the 
first 11 numbers.
In order to obtain the freedom of the planet into 
whose current he has been drawn, he is obliged to 
take an oath, and it indicates the first sacrament, 
that of Earth. He thus obtains freedom to seek for 
a suitable medium for incarnation, indicated by the 
words "Be seated on my right hand." He is presented 
with a sacred scroll which confirms his freedom. It 
should have been remarked that the penalty of the 
oath applies to reproduction or generation.
The Soul is attempting to perform its work through 
the vehicles of humanity and if it fails to hold 
those mysteries sacred and secret, it will lose its 
power to employ this vehicle for its work.
The meaning of the sign and of the word ON have 
already been explained in the Lecture of the Fourth 
Degree, but there is further meaning in this word, 
which is heartily recommended for your profound 
study. A strong hint may be given by the study of 
the number 120. Its character should be written in 
Arabic.
It should be noted that Saladin is supposed to be 
seated in a tent and this tent should be in the 
shape of a cone, a geometrical figure which 
combines the straight line with the circle.
The new Minerval is informed that he is in need of 
repose, which refers to a period of contemplation 
necessary to the beginning of incarnation. The 
suitable lodging refers to the suitable human 
beings with whom the soul proposes to take up its 
residence. Its further adventure is detailed in the 
I°.
First Degree
We left the Minerval within the attraction of the 
Planet prepared for incarnation, but I have not 
taken any detailed steps. The I° describes this 
operation. I shall not here deal with the opening 
and closing of the [Oasis] as that is only a 
ceremonial estimation of the place and that 
pertains to another matter. The [Oasis] represents 
the World. [The noose] refers to the umbilical 
cord. The Candidate is received on the Dagger which 
signifies that he has asked for admission into a 
hostile world, and also refers to the cutting of 
the [noose]. He is asked whether he is free and of 
full age. His incarnation must be a deliberate act 
of free will.
Isis is then invoked upon him, and this Divine 
permission having been obtained, the permission of 
Nature, he enters the world of conscious life in 
search of Father and Mother whom he finds. I the 
Father is a symbol of Ithyphallus; O the Mother is 
a symbol of Demeter, being the beginning of the 
prayer made in the ancient ceremonies.
In the next part of the ceremony the powers of the 
[Oasis] consent to the birth, the ego (being) 
incarnated with the words "In myself."
All this being happily arranged, the Candidate 
makes nine circles of the [Oasis], as it is said, 
on his travels with the Moon. He then makes a final 
effort, and comes to the Chair of the Master. The 
Clauses of the Obligation are those contracts by 
which he can obtain freedom. It will be noticed 
that this refers to water, for man is of Amniote, 
and naturally the penalty of the (first) 
obligation, water, is referred to. But, in his 
birth, his life passes from water to air, and the 
penalty is, therefore, that of having his throat 
cut, which would prevent his breathing.
[The dagger] is by shape an I representing the 
Father and the initial of Ithyphallus, while the 
[disk] is by shape an O, which similarly represents 
the Mother, and is the wheel of the word Oon, 
Oophore. The [V.S.L.] represents the [dagger] and 
the [disk] combined and by its square shape the 
Greek gamma, the initial of Genetor. It should also 
have been remarked that there is another 
attribution of the [dagger] and the [disk] 
precisely opposite to that given above. This is 
very necessary, as every symbol is only perfect in 
so far as it has its opposite. The Candidate is 
then brought to light and greeted by the powers of 
the [Oasis]. The [cutting of the noose has] an 
obvious meaning. The Candidate is now reminded of 
the penalty of his obligation. Although he is born 
he is still condemned to death. His hopelessness is 
then illustrated, and that being understood, he is 
permitted to use all his personal comforts, which 
he obtained from the room, that is to say from his 
Mother, the [Oasis]. In Egypt, where these 
mysteries were founded, sons derived from their 
mothers not their fathers.
The Candidate is then taught first to stand 
upright, the use of the foot; yod, the use of the 
hand. It would be improper on the present occasion 
to go more deeply into the signification of the 
Secrets. They being effected, the Candidate goes on 
his travels, this time with the Sun, i.e., on his 
life upon Earth, which he counts by days and years 
rather than by months. He is then tested in the use 
of his limbs and being found perfect, he is given a 
[black robe] made of [wool], referring to Aries, 
the ram, the sign of the Sun occurs at the Spring.
After this he is permitted to take his seat in the 
[Oasis]. He has an appointed place among men, and 
the powers of the world offer him a banquet in 
order to sustain him on his further journey. 
(Note the part about free will)  What do you guys think?
