...I came upon a booklet, written
in German by a certain K. Spiesberger, which contained various esoteric
techniques, among which included the Kundalini-breathing. I did not have much
familiarity with the German language, but I immediately realized the
extraordinary importance of that technique; I would undoubtedly decipher all of
it at home, with the help of a good dictionary. 5
The description of this technique still amazes me; the author, in fact, was
not as close to Lahiri Mahasaya’s Kriya as to the version of Kriya Pranayama
that P.Y. brought to the west. During a deep inhalation, the air was to be
imagined flowing up the spinal column, abandoning its habitual course; the
visualization of this as an empty tube was therefore prescribed and, while
inhaling, the air was to be imagined streaming along it from its base all the way
up to the area between the eyebrows; then, exhaling, the air had to go down back
to the base, along the same route. There was also the description of two
particular sounds that the air originated in the throat.
