The Sun is regarded as most powerful of all the planets and is master of many activities of human life. Sun gives good health, energy and success to mankind.
In situations of deprivation, worship of Sun through Surya Namashkar etc. is often advised. Difficult phases in life are meant to be overcome through the worship of this yantra. When the Sun is malefic in one’s birth chart or according to the rashi based on his name, the Surya Yantra becomes particularly useful.
