Moreover, knowledge or skill in the
material world does not necessarily include that of the spiritual
realm, so a lack of it may not exclude it either. Hence the ancients
could very well have had quite a diversity of religious or spiritual
approaches even in a small area. Look at the philosophical diversity
we find in great ages of humanity like ancient Greece, though the
land itself was rather small. So too, we cannot judge the breadth of
ideas by the material limitations of a culture.
Probably the most universal and
comprehensive of such ancient teachings is the Rig Veda, the oldest
teaching of India. It is not surprising that it has been reduced to
such a polytheistic interpretation, though it states in many places
the unity of truth and the identity of one God with all the Gods.
The basis of all scriptures is a
rendering in human language of the Word of God. It is not our
culture alone which has a book it claims to be the word of God. Most
cultures have such a book. Some have many such books. The essence
then of a source teaching or scripture is a rendering the word of
God. This is called mantra in Sanskrit. By the spiritual origin and
power of the Sanskrit language many mantric or scriptural texts thus
exist within it. The most primary is the source book of the mantra,
the Rig Veda.
