Cleansing Techniques Bharat Thakur Yogis put a lot of emphasis on “Saucha” which means cleanliness. They understood that negative thoughts arise from an unclean system. For example, because of your sinus problem you might have a head ache and this makes you irritable. Sinus is a result of excessive mucus in your system and to remove it a powerful technique called “Jal Neti” can be practised to clear your nasal passage and make your breathing smooth and easy. This technique easily relieves your headache as well as migraine.
