Dwapara Yuga & Dewey Decimal

In 1876 the Dewey Decimal system helped to systemise knowledge in schools and libraries around the world. The top 1000 numbers defined the most important topics according to its deeply Christian inventor Melvil Dewey. Islam just makes it and Buddhism not at all. However, what is interesting is the very high emphasis given to finer energies (see below), completely in line with the dawning spirit of Dwapara Yuga in 1900.

Dewey Number and Subject
130 Paranormal phenomena
131 Occult methods for achieving well-being
133 Parapsychology & occultism
135 Dreams & mysteries
137 Divinatory graphology
138 Physiognomy
139 Phrenology

It was not until 1905 that Einstein postulated the relationship between energy and matter (E=mc2), the finer and finer aspects of which are still being discovered by scientists today.

Today, with Google, arguably these rigid hierarchical classifications are obsolete in the virtual world but in a physical world, Dewey facilitated the access to knowledge that fueled research for the last 6 generations, especially in patent libraries such as the Library of Congress in the US or John Rylands Library in the UK.
