He described the teaching
as "a structural anatomy of human inner force built by the seven purest
elements of natural inner strength". This knowledge was used for protection
against the wild surroundings, and also for maintaining peace and harmony.
With the Invention of war weapons the teaching in the book became less and
less practiced, until eventually lost and completely forgotten. In 1947 Tagashi
followed the map shown on the last pages of the book, believing this
to be the journey made by the person or persons,
who had last been the keeper of the book.
In
1907, Tagashi was traveling in the North of Tibet, there he found an ancient
leather bound manuscript written in symbolic form. For forty years he studied
the book and made an intensive search for its origin, comparing it with other
ancient books kept by the people of Tibet, Nepal and Himalayas. He named the
book the 'Seven Secrets', having translated the symbols into seven different
characters, originating from a time when wars were non existent.

During
the 16 years period of his journey through Nepal, India, Thailand, Malaysia
and Indonesia he taught some 200 students. The teaching was given in secrecy
to prevent them misusing the resulting knowledge.
In 1963 Tagashi arrived at Bromo Mountain in East Java, Indonesia. It was here
he discovered that the seventh secret could be achieved and was very much more
than the knowledge and ability already achieved. From this moment Tagashi's
aim was to stay in Bromo Mountain and find the link or method, which separated
the ability already achieved from the ultimate knowledge - the seventh secret.
During his six year stay from 1963 - 1969, some other students from Indonesia
met Tagashi. They stayed with him and later, were given the special task of
helping Tagashi find the key to unlocking the Seventh Secret. In 1969, one of
the students from Indonesia obtained permission from Tagashi to translate the
seven secrets into ordinary language, including the method of unlocking the
Seventh Secret, which had finally been discovered by this same student.
