The second posture, vajrasana, is described, and in its description stands a word more important than the posture itself: sama-griva-shirah-kayah, "with neck, head, and body even." This requirement stands first in every book on yoga and is repeated constantly; and it, unlike the rest, is obligatory in every posture. The Gita says it in the same words: "holding the body, head, and neck even, motionless, steady" — samam kaya-shiro-grivam (6.13). The coincidence is almost word for word, and this is no accident: this phrase is the common possession of all these books.
Let me say why this requirement is sound apart from any doctrine. A bent neck presses on breath and blood, and a man sitting bent soon grows drowsy. A straight back is not a feat: it is a condition of wakefulness; and anyone who has tried to read lying down knows the difference.
It is worth adding that the word vajra means "diamond" and "Indra's thunderbolt-mace" — that which neither bends nor breaks. The posture is named for firmness; and in this name one sees what is wanted of it: not flexibility, but immobility.
