The disease in this form is called Antarayatma Dhanushtambha. The movements of the eyes become impossible, which become fixed in their sockets; the jaw-bones become paralysed, the sides are broken, and the patient ejects (at intervals quantities of) slimy mucous (Kapham). These are the features which mark the first type (Antarayama Dhanushtambha). On the contrary, when the same enraged Vayu, centred or lodged In ligaments which traverse the posterior side of the body, attracts them violently, the body is naturally bent backward. The patient experiences a sort of breaking pain at the chest, waist and thighs, (which are ultimately broken). The disease Is called Vahiratyatma, and should be looked upon as beyond the pale of all medicinal treatment. 47 — 50.

Four types of Akshepaka are usually- recognised in practice such as, the (i) one incidental to the concerted action of the enraged bodily Vayu and Kapham (2), the one brought about through the union of the enraged Vayu with the deranged Pittam, (3), the one due to the single action of the agitated Vayu (4) and the one due to any external injury or blow (Abhighataja).*[1] An attack of Apatankah due to excessive haemorrhage, or following closely upon an abortion or miscarriage at pregnancy (difficult labour), or which is Incidental to an external blow or injury (traumatic), should be regarded as Incurable. 51 — 52.
