Siva Yogaswami (1872-1964) said in Natchintanai, at two places that I know of, the following:
(1) Even if famine and army come
Even if the land is burned by fire
We will not be in fear—oh parrot
Arumugan (Nallur Murugan) is our refuge
(2) When famine and army come—Vel Vel
Don’t fail to repeat Siva’s name (Namah Sivaya)
Siva Yogaswami had foreseen what is going to come in the future—the sufferings of Tamils in Sri Lanka, and He had given us hope and a way to relief ourselves from the oncoming Karma too: Nallur Murugan is our refuge, and Aum Namah Sivaya is our shield. It is really a heart warming feeling that the Nandinatha parampara is taking care of the suffering souls in Sri Lanka from this and the inner worlds.
THANK YOU SWAMIS.
