It is simply unbelievable but those cities had bathrooms attached to the bedrooms.
You will be surprised as to why this fact should be so important, but just in the last century – just a hundred years ago – when people in America started to make attached bathrooms, there was such a reaction from the masses that the government had to step in. There were cases in the courts claiming that it is ugly, unchristian, because cleanliness is second to godliness, and these people are doing something ugly – having a bathroom, a toilet, attached inside the house. It has always been outside the house; its name was the outhouse.
Seven thousand years ago those people were far more advanced in thinking – they had beautiful swimming pools…. And the most miraculous thing is that in Harappa and Mohenjo Daro they had a hot and cold running water system. It was a highly developed civilization. And they must have had vehicles big enough; otherwise there was no need to make such broad roads. They had big windows, which was rare; big doors, which was rare at that time; gardens….
According to Hindu scholars, the Rig Veda is ninety thousand years old. And the man who proved it, Lokmanya Tilak – one of the most intelligent Hindu scholars of this century – has proved it on such grounds that nobody has been able to argue against him – because he proved it on grounds not logical, but astronomical.
In the Rig Veda there is a description of a certain happening in the world of stars, a certain meeting which has not happened since then. The description is absolutely clear, and it would have been possible only if the people who were describing it had seen it. And in fact astronomy now agrees with Lokmanya Tilak – that it happened ninety thousand years ago, and the way it is described in the Rig Veda is exactly right – the way astronomical things should be described.
So astronomy was highly developed, and the people could see the conglomeration of the stars. They even described stars and planets which we have just discovered; otherwise, fifty years ago people were simply laughing, “Where are these planets?” Pluto and Neptune had not been discovered fifty years ago and people were laughing. “This is just fictitious!”
But now they have been discovered with better instruments; more and more stars, more and more planets have been discovered; and they are all fitting together with the chart that is given in the Rig Veda.
The Rig Veda mentions Rishabhdeva’s name with great reverence. I am emphasizing the words great reverence because Rishabhdeva was not a Hindu. He was born a Hindu but he was starting to disagree with Hindu philosophy, Hindu doctrines, and he was originating a new religion; he was the source of Jainism.
