Mantras contain various types of strength. We sometimes feel that Mantras
are simply a collection of words without any specific strength. The power
behind the Mantra can be understood only by those who are well versed in them.
Although we are not able to see directly the connection that exists between the
divine and the humans, yet as a Paroksha or by inferential evidence, we are
able to feel that there is a connection between the divine and the human
through the Mantras. In simple things, like the machines which are created by
man, while we see direct evidence of their strength, to think that the Mantras
created by God do not have such strength in them is not correct.
