Q: What are the necessities of the sky direction according to Vastu Shastra?
Ans: According to geology there are eight directions. But according to Vastu Shastra there are ten directions, in which main four directions are north, south, east and west and there are four sub-directions and these are north-west, north-east, south-east and south-west. There are more two directions, i.e. sky and down.
Cosmic ray comes from the sky. According to Vastu Shastra this is ninth direction. This ray is limitless. Throughout the time this ray is available. But solar ray can be available only while it is day and it is maximum 14 hours. Cosmic ray is available irrespective of day and night throughout the time. The particular characteristic of the cosmic ray is that it can enter the earth. So Vastu Shastra gibes abundance to the sky.
