Please note that the content of this book primarily consists of articles

rendered in English as "yoga sleep". It is a sleep-like state that
occurs with some practitioners of meditation, details of which have been
handed down by guru-to-disciple transmission (parampara) within the
Indian religions. These aspects may include relaxation and guided
visualization techniques as well as the psychology of dream, sleep and
yoga. Yoga-nidra should not be confused with hypnotic states, known as
"yoga tandra".The practice of yoga relaxation has been found to reduce
tension and anxiety. The autonomic symptoms of high anxiety such as
headache, giddiness, chest pain, palpitations, sweating, abdominal pain
respond well. It has been used to help soldiers from war cope with PTSD.
