Just as Agathiyar started me doing Jala Neti a couple of days ago when I was introduced to the Nasal Rinse Kit, a modern improved version of a Neti pot, which I used to clear my sinus infection successfully, Agathiyar had previously recommended various therapies to maintain ones health in the Nadi.
Agathiyar had recommended my daughter to gargle her mouth with sesame oil upon arising from bed. I Google to find out why Agathiyar recommended this therapy and came across the following revelations at http://www.medicinenet.com/sinusitis/article.htm and http://www.ehow.com/how_8261687_sesame-oil-pulling-instructions.html. I was surprised to know the enormous amount of benefits one acquires by just doing this very simple therapy.
Another therapy that Agathiyar recommended, again for my daughter, was to soak her feet and hands in a basin of warm water premixed with sea salt. Check out http://www.himalayanlivingsalt.com/himalayan_crystal_salt_bath.htm to learn about its benefits.
When my daughter broke her leg, Agathiyar asks her to consume sesame seeds in any form. As we were wondering why sesame seeds, Mr Google comes up with the answer. The high calcium content in sesame seeds helps the bones mend. See http://www.care2.com/greenliving/how-to-benefit-from-nutritious-sesame-seeds.html
Besides that Agathiyar had recommended herbal medicines too through the Nadi. Jeeva Sakthi Lehgiyam, Vallarai Lehgiyam, Tripala, and preparations with Indian Gooseberry or Nellikai.
Yogi Ramsuratkumar used to advocate the consumption of gooseberry to devotees.
Ma Devaki writes in YOGI RAMSURATKUMAR - THE DIVINE BEGGAR,
He (Yogi Ramsuratkumar) was always an ardent champion of gooseberry and he advised, "It not only improves one's memory power and concentration, it also helps to develop body immunity. It is a tonic and panacea for all ills." He laid emphasis on Nama (chanting God's name) for all ills of the mind and gooseberry for all ills of the body.
Tavayogi Thangarasan Adigal passed on a set of Asanas and breathing techniques to some of us while he was in Malaysia. Muralitharan Saminathan, Thayalan Arumugam, Sathiswaran Arumugam and I managed to film him performing this asanas and techniques. Later Agathiyar tells me in my Nadi reading that what Tavayogi had given was a Pokkisam or treasure. When Thayalan discontinued practice of these techniques, Agathiyar reminded him of its efficacy and asks that he continue doing it.
