The reason you used the term as “Gharan Yoga” I thought you have some knowledge about Vedic astrology. Gharan means eclipse and when there is a conjunction between Rahu and Moon. This dosha or malefic aspect takes place. Having said that I feel you should do the simple remedy and that is.
1. Recite Mantra “OM NAMAHA SHIVAYE” minimum 108 times daily
You should sit in a Yogic posture and recite the mantra , with full concentration. This Vedic Mantra is very powerful to give you strong effects and reduce the malefic influence of these planets.
