During the influence of Aries, there are numerous exercises to develop ourselves spiritually, especially to charge our head with light in order to rejuvenate and awaken the pituitary and pineal glands, which provide the power of imagination, clairvoyance.
In Practical Astrology, Samael Aun Weor teaches several techniques to use during Aries. This is the easiest one:
"During this sign, the disciple should vocalize the vowel “I,” daily for one hour, like this: Iiiiiiiiiiiiiiiiiiiiiiiiiiiii..... (as in “see”) This vowel will cause your pineal gland to vibrate, and finally you will become clairvoyant. When developed, the pineal gland converts us into super-humans, and when atrophied, it converts us into idiots. The pineal gland is found developed within the chaste, and atrophied within the fornicators.
"...every night before going to bed the disciple should practice this next exercise: Sit in a comfortable chair for half an hour. Close your eyes. Remove all thoughts from your mind. Then, imagine that the fire from the constellation of Aries is descending from heaven and penetrating the igneous columns through your pineal gland. The pineal gland is situated in the superior part of the brain and the power to see the ultra of all things resides in it...
During these exercises, the disciple will be assisted by the hierarchies of Aries; they will awaken his powers and heal his brain with special treatments. The disciple may also be able to use the power of those hierarchies for the healing of others." —Practical Astrology by Samael Aun Weor
