Sculpture and dance
This whole theory of Indian sculpture is based upon dance and the theatre, and at first sight may not seem to have very much to do with either nature or sculpture. In fact, there is a profound inter-relationship. The expression of the forms of sculpture, the metaphors they contain are best explained in terms of dhvani. The 'latent traces' the forms evoke are visual and sensuous memories of all those other experiences—tree-trunks, fish in a pool, elephant trunks, flower petals are really only a few of them—whose emotional charge is added to the meaning of the sculpture. But there is an even closer connexion between the ideal theatre and the art of sculpture. For sculpture in India is intentionally tied to the expressive modes of the Indian dance-drama. It is also most probable that the art of the sculptor has exercised a reciprocal influence upon the dancer's art, of course; but this is a natural relationship. For there can be little doubt that the figure sculptures with which Indian temples are encrusted parallel closely the dancers who were at one time associated with the temples. Today only a few major temples, chiefly in the south, continue the tradition of maintaining a corps of dancers. Once, however, the practice must have been widespread. On the gateway towers of the temple of the dancing Shiva at Chidambaram.in South India, is preserved a complete record of the dance postures of the middle ages. They are carved in relief, in a series of bands. Their sole religious significance is that at certain times of day the resident corps-de-ballet performed dances before the shrine, which were based upon the divine legends of Indian mythology and literature. Hence dancers were constantly 'realizing' the roles of the deities of the legend.
The temple dancers, the devadasis, were also available, at a fee, to perform for those who could pay; and the temple corps-de-ballet overlapped with the court troupes of the local princelings. So that, in fact, the visual experience of sculpture was always intimately related both to that of the dance, and of love.
Thus, what we have to look for in Indian sculpture, granted the sensuous, haloed quality of the sculptor's forms, is a further kind of expression. Again it is not easy for Westerners to read it— especially since modern art has more or less forbidden us to look at figurative art with the right kind of attention and interest.
What we have to look for is the mimetic expression of the whole figure. And we must remember, too, that the human figures represented in Indian sculpture are always engaged in some mimetic expression. Even those figures which may seem to us to be sitting or standing doing nothing in particular are, in fact, intended to be expressing repose', or ease', by all the postures of their body and limbs. All the figures are always 'on stage', as it were. They are sculptured dancers embodying their roles with all the resources of the Indian dance. But whereas human dancers will have, by the mere fact that they are human, all those lapses from ideal canonical beauty which are inseparable from humanity, bodily defects which mar the completeness with which they can convey the essence of their roles, the sculptured dancers are embodied in forms which are wholly apt to what they have to express. It is not that the sculptures refer to actual dancers.  They really represent 'the dance' as something outside and beyond themselves. With sculptures there is no danger of the spectator reacting as to a real person. But they do share the resources of the dance in this sense—that they evoke groups of memory traces, by presenting the 'effects'—postures, gestures, expressions—of 'causes'—i.e. people once experienced emotively in various expressive guises—and among their means are static images of gesture and posture, as well as form. The dancers themselves are so generalized in type, so idealized, that there is no mere human likeness left in them. They are ideal images of ideal dancers. Thus, sculptured figures will act as determinants in all sorts of ways, displaying evolved evocative symbols of social communication in their forms, and in their dance-gestures as figures.
Of course, the figures shown in sculpture are deprived of actual movement. Among the canonical postures and gestures of the Indian dance a few depend upon actual motions of body, head, arms, hands, eyes and eyebrows. It is for these that the dhvani qualities of form, the suggested aura of significance, must compensate. But most of the repertoire of the Indian dance consists of static positions combined and presented in a sequence of image-units. Hip postures, leg-positions and arm-positions are relatively few in number. So, too, are the head positions. In combination, however, they can express an immense variety of situations. However, the greatest wealth of meaning in the Indian visual arts is conveyed by the hand gestures, called mudras. These, one more function of the magically versatile Indian hand, have been elaborated into alanguagesorichand subtle that entire narratives can be carried through in mime alone—no setting or explanation is necessary. Of course, for the gesture language of the dancer to be understood demands that the audience be accustomed to reading the language of the hands. And this is not easy for Westerners. Very few have attained the necessary degree of skill, demanding as it does constant practice.
Such gestures, of course, are in the highest degree stylized. They must, at some distant period of time, have evolved from a mixture of observation, custom and creative analysis. So that there is a kind of residue of immediate emotional expression in some of them, as in the open-palmed hand, stretched downward, which indicates 'giving', or the pointing hand that indicates compulsion or driving. Others are obviously formally imitative, such as the clenched fist with first and fourth fingers erect whose primary meaning is the cow (horns on the head), or the upward-pointing hand with straight fingers gathered together, which indicates the closed lotus-bud, and all its associated meanings.
How wide such a range of meanings can be appears, for example, with the Sola-padma hand (also called Ala-padma), representing the full- blown lotus-flower in which the fingers are separated and curved. This means the open lotus, a fruit, turning, a breast, mirror, full moon, yearning for the beloved, a golden cup, a hair- knot, a moon-pavilion, a village, height, anger, lake, chariot, a chakravarka bird, murmuring sound or praise—according to context, and according to the hand and postures with which it is combined. A pair of Ala-padma hands, for example, held on the chest and twisted upwards, means husband, humble words, the breasts, 'I am beloved', conversation, and indicates desires. Held to the eyes, such a pair of hands indicates large clusters of flowers; to the head a sal tree, or a mountain. The possibilities of such combinations to express emotions, objects and action seem endless, and have been preserved from teacher to pupil through the centuries. Such things as fear, discussion, circumference, a partridge, actor's costume, slowness, impartiality, light food, concealing a child, sprinkling, shooting, testing prepared medicine, listening, winding, milking, are commonplaces of this subtle hand- language.
