"The Venustic Initiation is only for true human beings, never for intellectual animals. Let “true human beings” be understood as those who already created the solar bodies. Let “intellectual animals” be understood as all of humanity, all the people who only have lunar bodies. The Venustic Initiation is the true nativity of the tranquil heart. The Venustic Initiation is for the few; it is a grace from the Solar Logos. In Nirvana, there are many Buddhas who—in spite of their great perfections—have never reached the Venustic Initiation." - Samael Aun Weor, Light from Darkness

The Venustic Initiations are the Seven Serpents of Light of the First Mountain plus one more related with the Sephirah Binah. Read The Three Mountains.

"...the Venustic Initiation that has eight grades. The first Venustic Initiation is just the superior octave of the first initiation of fire. The second Venustic Initiation is the superior octave of the second initiation of fire. The third Venustic Initiation is the superior octave of the third initiation of fire. The fourth Venustic Initiation is the fourth superior octave of the fourth initiation of fire. The fifth Venustic Initiation is the fifth superior octave of the fifth initiation of fire; after this come the three initiations (the total is eight) that are related with the First Mountain (that is the First Mountain). In the Second Mountain one has to begin the work with the Moon, with Mercury, with Venus, with the Sun, Mars, Jupiter, Saturn, Uranus and Neptune, to then achieve Perfection in Mastery (it is the Mountain of the Resurrection), and the Third Mountain is the Ascension, to finally crystallize (in oneself) the Second and First Logos, and to receive the Inner Atomic Star." - Samael Aun Weor, The Master Key


"...the Kingdom of Heaven can only be taken by energy."
