Syman begins
The Subtle Body by describing in turn the precursors of
American yoga, namely
Ralph Waldo Emerson and
Thoreau. She notes that Emerson's 1856 poem
Brahma concisely introduced
Hindu nondualism, repudiating "sacraments, supernaturalism, biblical authority, and ... Christianity". Thoreau, she states, tried to practice yoga, and was seen by some as "the first American Yogi", but by others as "a misanthropic hermit". However, Syman identifies the dramatic From there, she presents the showman
Pierre Bernard and his relative
Theos Bernard, including sections detailing Pierre confusing yoga with
tantric sex, complete with "lust, mummery, and black magic", and of Theos telling
a carefully fictionalised account of his experiences with
Hatha Yoga in India and Tibet. The book then includes stories about a variety of straighter advocates of yoga. Syman tells the story of
Margaret Woodrow Wilson, daughter of American president
Woodrow Wilson, writing how she "turn[ed] Hindu" after she "found peace" in
Sri Aurobindo's
ashram in
Pondicherry. A
Hollywood connection is then explored, featuring
Prabhavananda, who translated the
Bhagavad Gita;
Aldous Huxley;
Alan Watts; and
Indra Devi. The books explains how Devi came to America, unknown, having learnt yoga directly from
Krishnamacharya, and how she had grown up in pre-revolutionary Russia, escaping to Berlin and going to India with her diplomat husband. It also tells of the times that Devi taught many celebrity pupils, including
Greta Garbo and
Gloria Swanson; in a review, Sarah Schrank notes that Syman is interested in how "American fans, often rich and female", made suitable environments for yoga to spread, "shaping celebrity gurus in the process". It then tells how they were followed, towards the end of the 1960s, by Indian gurus of
postural yoga, such as
B. K. S. Iyengar, founder of the precise
Iyengar Yoga, and
Vishnudevananda, founder of the more overtly spiritual
Sivananda Yoga, along with
Swami Satchidananda, giving the story of how the Swami made the crowds chant "
Hari Om,
Rama Rama" at the 1969
Woodstock Festival. The book ends with an account of the gurus of more energetic forms of yoga, in particular
Bikram Choudhury and
Pattabhi Jois. ==Publication==
