What is the purpose of kalinkam a herbal liquid pouring into eyes?
I think u heared roughly this through "Manavalakalai of swami vedathri maharishi" or so called "vazlha valamudan". All the general public practising swamy s meditation and yoga must be knowing about this.Even i pour this . I feel my vision improve better.It is a very pious medicine for eye problem and skin diseases.If the Kalikam u mention here is same as i have it in mind, u can pour it and see the results.
No juice should be put surrounded by the eyes . The juice u mentioned is a bogus article mad by a fraud solely. Once eyes r gone , they can't be replaced. Be careful.
