Did SSSIO ever report to SSSCT?

No. In the beginning there was a small office in Prasanthi Nilayam with three members. Reports of the SSSIO were sent to that office, not to the Central Trust. After Swami set up the Prasanthi Council, all international reports were given to Swami directly. Swami never told Prasanthi Council members to report to the Central Trust or to any member of the Central Trust.
