This living spirit remains within the body just like a tiny dose of a potent medicine: the soul spreads its presence all over the body. And thus, we can understand, the sensitivity we experience to even the slightest touch on any part of the body is due to the spreading of this living spirit throughout the body. But when this minute quantity of living spark is gone from the body, the body lies dead, prostrate, and it cannot feel the slightest pain—even if hacked by an ax.
That this minute living spark, the spirit, is not a material thing is proved by the fact that no material scientist has ever been able to create the living spark by any combination or quantity of material substances. Experienced material scientists have been obliged to accept the fact that the living spark cannot be duplicated by material science. Whatever can be created by the manipulation of matter is destructible and temporary. In contrast, the living spark is indestructible, precisely because it can never be constructed by any combination or quantity of matter. We can produce material atomic bombs but not the spiritual spark of life.
There is much advancement of material science all over the world, but regrettably, these advanced scientists have made no attempt to understand the living spark, the spirit, which is always the most important subject. This is our gross ignorance. This is our helplessness.
Śrī Jagadish Chandra Bose, Sir Isaac Newton, Benjamin Franklin—the brilliant brain substance of each of them stopped working utterly, as soon as this little spark of living substance separated from their respective bodies. If it were possible to create this living substance by chemical or physical combination or permutation of matter, then surely some disciple or other of these great scientists would have brought them back to life and would thus have prolonged their scientific contribution to the world. But no material scientist can create the living spark by any material arrangement, and those who say they can do so in the future are the greatest of fools and hypocrites. The living spirit is eternal—he has no end and no beginning and thus can never be created by any method whatsoever. After all, it is within our experience that every created thing is subject to annihilation. The eternality of the spirit soul is proved through its noncreatability by material means.
