Yes, I spoke with them earlier this year.(roja Muthaiah Library). They claimed Rs.5000 for each of his work (shuddhanandha bharati). Copyright is with the Shuddhanandha Yoga Samaj, and so I was wondering, "Tirunelvelikkey Alwaava?" and left it as such. If you have the other set of books you told me here in Chennai, I can come to collect the same.
