I can't personally recommend the lectures, since I have not watched them, but I have carefully read the book and taken notes: it is pure gold.

I can't find it in paper version though - only PDF. Any idea where could I buy it ?
I did have the opportunity to compare my PDF with a genuine original book, and found no differences. Even the typos I found in the PDF that I thought must be OCR errors turn out to be in the original as well.

The Wikipedia entry on Sargant says things like "his reliance on dogma rather than clinical evidence have confirmed his reputation as a controversial figure whose work is seldom cited in modern psychiatric texts.", and others "described him as 'autocratic, a danger, a disaster' and spoke about 'the damage he did'".
