Various devices are recognized to help the movement of the intrigue, five of which are classed as internal junctures (antarasandhi). [633] The first of these is the dream, as in the Veṇīsaṁhāra where Bhānumatī is terrified by a vision in which she sees an ichneumon (nakula) slay a hundred snakes, dread presage of the fall of the hundred Kauravas before the attack of Nakula and his brothers. The letter serves in the Çakuntalā, Act III, to allow the heroine to express her feelings towards the king; she reads it aloud and he overhears it and breaks in upon her; more often it serves the important end of conveying news, leading to dramatic action. A message serves the same end, as when in the Çakuntalā, Act VI, Mātali brings to the king Indra’s message imploring aid against the demons. A voice from behind the scene (nepathyokti) in Act I of that play warns Duḥṣanta not to kill the gazelle of the hermitage, and a voice in the air (ākāçabhāṣita) in Act IV makes known to Kaṇva on his return the important news of Çakuntalā’s marriage and approaching motherhood. The Nāṭyaçāstra [634] ignores the term internal junctures, but has the term special junctures or divisions of junctures (sandhyantara) which includes the dream, the letter, and the message, among many other miscellaneous elements; two of these are akin to those already mentioned. The picture is used in the Ratnāvalī as the mode by which the heroine satisfies her longing for her beloved, while Vāsavadattā discovers Vatsa’s infidelity through seeing the portrait of Sāgarikā, painted beside that of the king by the mischievous Susaṁgatā. Intoxication (mada) may result as in the Mālavikāgnimitra, Act III, in the letting fall of imprudent words by an important character. Other devices might have been included in the list, such as that of assuming a disguise on the stage, a device used by Harṣa in the Ratnāvalī and the Priyadarçikā in order to secure the inconstant king uninterrupted interviews with the objects of his temporary affections. The latter play contains in Act III a good example of the embryo Act (garbhān̄ka), [635] which is recognized by the theory but not classed as a species of juncture; in it Vāsavadattā causes her maids of honour to perform before her a play representing her early adventures with Vatsa. So in the Uttararāmacarita Vālmīki has performed by the Apsarases before Rāma and Lakṣmaṇa the adventures of Sītā since her banishment, and the events of her marriage are described in this form in the Bālarāmāyaṇa, Act III.
