During 1800s, Anthropologists had a problem as to
how to classify human beings. One researcher
proposed the expression "intelligent animal".
After advanced studies on monkeys, it was dropped.
Another researcher proposed "tool using animal".
After observing some animals making wooden tools
and sharpening them with knife like stones, it was
dropped. Another researcher proposed "weapon using
animal". A decade ago, a rare film was shot by an
amateur in an African forest. One short monkey was
hit very badly by a big monkey. The short monkey
prepared a wooden knife using stones and hid it on
the top of a tree. After some days, when the big
monkey came to attack the short monkey, it ran up
to the tree for the weapon it has hid and killed
the big monkey. The one thing that the
anthropologists found with any group of human
beings, even if they did not have contacts with
the out side world for thousands of years, has
spirituality with some form of religion. So, man
is a "spiritual animal" if you want to call him
that way.
The Upanishads say that "Manush" (human) was so
named because he has "Manas" a mind higher than
that of the animals which realizes the divinity in
creation. It was present since the creation of
human beings. Religion is the characteristic
feature of most of the human beings. It was not
attained through reasoning using mind. Illiterate
tribes located in inaccessible forests also have
religion. It is as eternal and and as unchanging
as the Almighty. Disbelief by a few will not
affect it.
