Architectural and symbolical relations between the Śikhara and the crowning part of the stūpa: Simplified elevation of an Orissa Śikhara (fig. 3) with its five Bhūmis, comparable to the Rūpaloka-bhūmis of the Bud hist psychocosmos, repreented by the spire of a stūpa with tentative reconstruction of an Āmalaka-kalaśa-termination (Fig. 21. Fig. I shows a slmilar termination of a modern Nepalese stūpa. The combination of Āmalaka and Tripatadhāra (Fig. 5) has been preserved in the termination of the Tibetan stūpa (mchorten) (Fig. 6). Tripatadhāra is here replaced by an honorific umbrella from which most probably it has been derived. The shape of the Tripatadhāra is exactly the same as that of the original honorific umbrella (Fig. 4 and upper part of Fig. 5).
