Andrea Bertolini was born in 1962 in Milan, Italy. He has been involved in spiritual research since the age of 20. He traveled to all five continents in search of the sources of Initiatory Wisdom, studying with different masters, both Eastern and Western traditions. After a long experience in Zen Buddhism and in a Western shamanic school, in 2001 he met Giovanni Maria Quinti continuing his path in the tradition of the Fourth Way. He is part of the La Teca-Institute for Harmonic Development Association, with which he collaborates as a trainer, conducting seminars and conferences on esotericism, in particular on Gnosis and Alchemy.
