Yes, Meditation should be a part of any Esoteric practice.
From the
Dream Yoga Course

This course offers the essential instructions so that anyone, anywhere, regardless of any distinctions or qualifications, may enter into their
own direct knowledge of the living realities that surround us, yet remain inaccessible to the physical senses.
Although interest in this subject is growing, there are many people who have been frustrated in their attempts to enter into this knowledge. Reading
books or attending seminars usually leaves the seeker with more questions, doubts, and contradictions. To those persons, we offer the following quote:
We have given many clues in order to consciously travel with the Astral Body, so thousands of students have learned to travel in their Astral Body.
However, we have seen in practice that those people who cannot quiet the mind, not even for an instant, who are accustomed to hopping from school to
school, from lodge to lodge, always inquiring, always preoccupied, are not able to consciously Astral Travel. - Samael Aun Weor, The Aquarian
Message
Therefore, in order to complement the course in Dream Yoga (Astral Travel), it is recommended that you learn how to cultivate a quiet mind.
Before anything else, comprehend that in order to consciously travel in the Astral Body, the process of thinking is an obstacle. - Samael Aun Weor,
The Aquarian Message
In order to assist you in the development of a quiet mind and a potent technique to understand oneself, we recommend our course entitled
Introduction to Gnostic Meditation.
True illuminates have no dreams. Dreams are for those who are asleep. True illuminates live in the higher worlds, out of the physical body, in a
state of intensified wakefulness without ever dreaming. - Samael Aun Weor, Mental Representations
We also ought to be able to awaken Consciousness through-out the day, by observing ourselves and our surroundings, without interference from the
mind.
When we meditate, we receive information from 'The Lord God of Truth Within' and thus carry out our actions in service of The Being(God).
Too many people want to do things in accordance with their egos, instead of Their Being.
Frankly put; this makes us Black-Magicians(practitioners of Goetia).
It is the ego that wants fantastic experiences. But if we meditate, our Inner-God will give us these experiences for our own good(and the good of
others), when we are ready and deserve them.
Through meditation and chastity, we can Be Thuergists(etymology = "God's Work") or "White-Magicians" instead of Demons.
