I remember Rawat saying it fairly often.  It was part of his sales shtick and he usually said stuff like "Keep me in your back pocket".

But Joe's right about things getting more intense in the late 70's.  That's when the heavy guilt trips started.  Before the official "space out" of '75/'76, we all pretended that we were happily learning to surrender ourselves without compromise in exchange for God-realization.  When things loosened up we admitted to ourselves and each other that maybe we weren't quite so single-minded about all this shit as we'd once thought.  Rawat then beat us over the head with our now-admitted "weakness" and "impurity" of purpose mercilessly.  That was what the late 70's were all about in this cult: guilt.
