The names for the asanas come from the
Sanskrit words ("crane") or ("crow"), and meaning "posture" or "seat". While different yoga lineages use one name or another for the asanas,
Dharma Mittra makes a distinction, citing Kakasana as being with arms bent (like the shorter legs of a
crow) and Bakasana with arms straight (like the longer legs of a
crane).
B. K. S. Iyengar's 1966
Light on Yoga describes only Bakasana, with straight arms. In
Sivananda Yoga,
Swami Vishnudevananda's 1960
Complete Illustrated Book of Yoga describes only Kakasana, with bent arms. However, practitioners in the west often mistranslate the Sanskrit "Bakasana" as "Crow Pose". These balancing poses can be dated at least to the 17th century
Hatha Ratnavali, where Bakasana is number 62 of the 84 poses said to have been taught by
Shiva. The 19th century
Sritattvanidhi, created for a Raja of Mysore, describes and illustrates both Kakasana and Bakasana. Norman Sjoman suggests that
Krishnamacharya, teaching in the
Mysore Palace, may have derived asanas including these from the 1896
Vyāyāma Dīpikā exercise manual. In his 1969 book
Asana Pranayama Mudra Bandha,
Swami Satyananda Saraswati of the
Bihar School of Yoga uses the name Bakasana for a different pose entirely (
Dandayamana Janushirsasana, pose 5 in Bikram Yoga). File:Kakasana in Sritattvanidhi.jpg|Kakasana, Crow Pose, in the 19th century
