So sāṅkhyam. Sāṅkhyam means... Sam means complete, khyam means description. "Complete description of creation." Kāla-viplutam, there is complete description how the cosmic manifestation is created, but people forget it, kāla-viplutam. So this knowledge is existing since the time of creation. Everything materially created has got six stages. The first stage is creation, and the second stage is growth. The third stage is maintenance, the fourth stage is production, the fifth stage is dwindling, and the sixth stage, vanishing. This is anything material.
The scientists, they are very much busy. Just this morning our scientist, Svarūpa Dāmodara, was speaking about an article: the scientists are very much busy that the source of supply is being decreased. Just like petroleum. Petroleum, gas, that is diminishing. Now, whole modern materialistic civilization is depending on the motorcars and aeroplanes, transportation. So if the petroleum supply is stopped, then what will be the condition of the society? Formerly there was no need of going to see a friend thirty miles away, because every friend was within the village. Now, because we have got motorcar, we create friendship with a man who lives fifty miles away. We accept a job fifty miles away. In Hawaii our Gaurasundara was going to attend office fifty miles off. By fifty miles off... In big, big cities like New York, Calcutta, we have seen people are coming to attend their office from hundred miles off. I have seen also in aeroplane there are many people... I have seen in England. Many workers or gentlemen, they are coming from Glasgow to London for working, by aeroplane.
