So you see, the advancement of our world has been brought about by the diligent effort of those so-called practitioners, the bearers of light in this world - the yogis, the realized ones, the mahatmas, the masters. Those greater ones are more beneficial, are working in a greater dimension. But even the so-called less high level yogis, practitioners, bearers of light, are also making their contribution to the whole atmospheric change in our world today. If these practitioners of light, bearers of light, did not exist and had not been existing throughout the centuries, then our world would not have come to this condition as it is now. So we are grateful to science and its discoveries for all our comforts and all the advanced apparatus. But we truly forget what is the 'behind' benefactor, the invisible one, which brought about this condition.
If these so-called practitioners or bearers of light were absent from our world environment, then the world would become like hell. There would be no symbol of virtue, no examples of higher living, no light. It would be like a countryside without any electricity, all dark, like in the olden days. Therefore, what makes our world different from hell is that we still have light-bearers; and what makes our world different from heaven is that the light-bearers, the virtuous people are fewer in number. That's what makes all the difference.
