Shri Mahant Swami Ganeshanand Saraswati Giri (ca. 1895–1988) was known to all who loved and studied with him simply as Ganesh Baba. At the age of four, he was brought back from death through an initiation by Lahiri Mahasaya and through this initiation descends from the same Kriya Yoga lineage as Paramahansa Yogananda. He became a swami under his guru Sivananda and later went on to run the Anandamayi Ma ashram. Drawn to the life of the Naga Babas, he became the head of the Ananda Acharya, Naga followers of Lord Shiva who consider cannabis and other entheogens to be the gift of the gods. The unique set of principles and exercises Ganesh Baba developed from the tantric practices of traditional Kriya Yoga and Shivaism became the core of his personal teachings of Crea (for creative) Yoga. Ganesh Baba's message of systematic synthesis of the spiritual and secular was carefully developed for and embraced by contemporary students in the 1960s, especially those whose path included the use of entheogens. This book contains the core of Ganesh Baba's Crea Yoga teachings, from the beginning stages of conscious control of one's posture, breath, and attention to finally extending one's awareness to the farthest reaches of the cosmos. Eve Baumohl Neuhaus shows that the life of this scholar and crazy saint was as instructive as his teachings. She includes many personal reminiscences of this inspirational and challenging teacher from her own life and those of fellow students, which demonstrate that Ganesh Baba's extraordinary life was in keeping with his own role as the embodiment of Lord Ganesh, the remover of obstacles.
