which should be ascribed to the action of the deranged Pitta in concert with the vitiated blood. 12.
The different colours of the pupil in cases of Linga-náśa:— Now we shall describe the colours of the pupil in the six different types of Linga-náśa. The pupil assumes a reddish (Aruna) colour in the Vátaja type of the disease; looks blue or bluish yellow in the Pittaja, white in the Kaphaja and blood-red in the blood- origined one, while it assumes a variegated hue in the Sánnipátika type of Linga-náśa. A circular patch (Mandala) tinged with a shade of bluish or bluish yellow colour and looking like fire or a piece of thick grass, is formed on the pupil owing to the diseased and aggravated condition of the blood (with pitta) in a case of Parimláyi. In this case the patient is sometimes permitted to catch faint glimpses of the external objects owing to the spontaneous and occasional filtering away of the deranged Doshas obstructing the vision. 13-15.
Specific Traits of Linga-náśa:— The circular patch (over the pupil) in a case of Vátaja Linga-náśa is red-coloured, and is moving and rough to the touch, while that in a case of Pittaja Linga-náśa is bluish or yellow or coloured like bell-metal. The circular patch in a case of Kaphaja Linga-náśa is thick, oily and as white as a conch-shell, a Kunda flower or the moon —resembling a white drop of water on the moving lotus leaf and moving away to and fro when the eye is rubbed. The circular patch over the pupil in a case of Raktaja (blood-origined) Linga-náśa is red-coloured like a coral or a (red) lotus-petal. A Sánuipátika type of the disease is marked by a variegated colour of the Drishti (pupil) and by the specific symptoms of the different Doshas. 16.
