The compound like structure around the temple complex is termed as “Mālikā” in the scriptures. While defining the term Mālikā, Kāmikāgama gives the following explanation.
शालायामपि शालाङ्गा निष्क्रान्ताननशोभिता।
सा शाला मालिका ज्ञेया शास्त्रेस्मिन् कामिकाह्वये।।
Part of a śālā with beautifully projected front portion is termed as “Mālikā” in this scripture with name “Kāmika”.
Thus the definition of Mālikā is found in the āgama. The Mālikā can be considered as one of sabhās. Mālikā is divided into three based on its place viz Prāsādamālika, Muṇḍa mālikā and Saudha Mālikā. Further it is divided into three as Sañcita, Apasañcita and Upasañcita. The another division is Drāviḍa, Nāgara, Veśara, Jāti, Chanda, vaikalpa, śuddha, Miśra, saṅkīrṇa, Bījamūla and aṅkura. The mālikā can have ambulatory path or it can have ṣaḍvarga (six limbs) as seen in a vimāna.
According to the structure, they are divided as Lāṅgala mālikā, Maulikāmālikā and Padma mālikā. The Padma Mālikā too has so many variations. A Aṅkaṇa is left between the prāsāda and the Mālikā. The Mālikā can have śālās or sabhās in between them. If the interval place between two śālās has a hārālaṅkāra, then it will be called as śrivardhanam. If the header is not available then the Padma mālikā is called as Saubhadram. If the header is of sabhākāra type, then it is termed as śrībhadra. If the aṅkaṇa place is doubled and doors are placed on east and west, then it is called as Bhadrasundara. If the header is of sabhākāra type, then it is called as Merukānta. If the above measurement is doubled with doors on front and back with karṇakūṭas on the intervals, then it is called as Sumaṅgalam.
If the Mālikā structure has Khaṇḍaharmas on outside projected upto one fifth of its length, with a wall on the back side and kūṭas on interval, with vimāna typed mukhaśālā on the front then it is called as Vardhamāna. If the header is not available, then it is termed as Manoramya. If the header is of sabhā type, then it is called as śrikara. Other types are the variations of śrikara.
If we analyse the Mālikā structure of Tiruviḍaimarutūr, then we can identify the same with the Vardhamāna type of padmamālikā. It has Khaṇḍa harmyas with a śāḷā śikharas and hārāntaras are depicted in the intervals. The khaṇḍa harmyas are of ṣaḍvarga type. The mālikā thus identified as Vardhamāna of padmamālikā type. I couldn’t see the vārsthala since I could get the picture.
The Mālikā of kailāsanātha temple too is of vardhamāna type, but the khaṇḍaharmyas are projected inside and not outside.
