Becoming Your Own Therapist and Make Your Mind an Ocean, by Lama Thubten Yeshe. This is a combined volume, second edition.
Becoming Your Own Therapist: Translated by Marly Ferreira. First published in 1998, this colection features three public talks on the general topic of Buddhism, followed by a question-and-answer session. Make Your Mind an Ocean: Translated by Luciele Rech and Anna Rech. These talks on the general topic of the mind were given during the lamas' second world tour in 1975. As ever, Lama’s timeless wisdom shines through, and his teachings are as relevant today as they were back then.

The Peaceful Stillness of the Silent Mind, by Lama Thubten Yeshe. Translated by Luciele Rech and Anna Rech. The six teachings contained herein come from Lama Yeshe’s 1975 visit to Australia. The first three are a series of consecutive evening lectures Lama gave at Melbourne University, and the last three teachings are public lectures given in Sydney. They are all filled with love, insight, wisdom and compassion, and the question-and-answer sessions Lama loved so much are as dynamic and informative as ever.
