Devotees offer water to the Sun in the morning, it will reach to the Sun God. Is it the myth or not would clear from the following incident:
Once there was the intelligent farmer who was taking GangaGanga
According to Bhagavata Purana, Vishnu in one of....
water and throwing it at the distance of 2- 3 feet away from the Ganga Bank. Villagers asked him that why he was wasting water, then he replied that as he was throwing water near the Ganga Banks it would reach to his fields 10 kms away from there. People started laughing at him that he had lost his mind. Learned farmer asked those villagers that when they were offering water to the Sun then how can, they would be sure that it would be reaching to Sun God.
Villagers replied that when they offered water to the sun there was the scientific reason behind it and cannot be compared with his activity of wasting water in lieu of the reason that it would be rushing to his field.
They said that they offer water to the sun from the brass or copper vessel with raised hands and pouring thin film of water from the height. The sun rays reached to them after filtering from the thin film of the water that sun rays are not only excellent for their eyes, but it would also revitalize their entire body and soul. The other reason is that when they concentrate on the stream of the water, then it can improve their concentration.
It is quite clear that it is not the myth. There is the scientific reason behind offering water to the Sun in the morning. It is the easiest way to thanks Sun as it is one of the main reason for life on earth. So now, if you offer water to sun you know the reason behind it.
