Kuḍalasaṅgama-Kṣetra & the Liṅga represents the Great Vyomavyāpī mantra of the Siddhānta tradition. Something many may not know is the fact that KN was once a great hub of Saiddhāntika Śaivam.
This a mantra of 368 syllables. But more importantly, it is a mantra of 81 words. In Śaiva metaphysics, the entirety of material existence (the “pure”, “pure-impure” & “impure” realms) can be mapped out in 6 various ways. 1 of those ways is the पदाध्व-
The other ways are listed here : The Grace of Siva that enables Maya – The Dance of Siva Nataraja
The Vyomavyāpī is considered supremely great because it encompasses ALL of “insentient matter” which is the raw material cause for the worlds, instruments, bodies & objects in the pure & impure dimensions.
How the 81 words map out to the 36 Tattvas & other such dimensions is something that I can’t elaborate here itself. I may do an article on it sometime though it is best grasped through a Guru steeped in the Siddhānta.
The mantra also has secret meanings, which have been expounded in Siddhānta scripture as well as by the Ācāryas. I had briefly touched upon this here, upon request:
To give a little more idea of its importance, it has to be grasped in the context of ritual. Here, that would be Dīkṣā (initiation).
In Siddhānta initiation, the soul, though all-pervasive, has to “climb” through the ontological ladder to reach the state beyond all insentient matter & bondages. Initiation allows this extremely complex act to happen with our own very imperfect bodies & limbs as tools.
What can possibly link acts happening at an infinitesimal, micro-level (our body, etc) & the realities of a grand ontological framework (all pervasive soul realizing its innate divinity by coursing through levels)?? The link is through the form of mantras.
We “call” those levels by employing the mantras meant for that level. We get an initiate’s soul to that level & make the soul enjoy the offerings of that level & then sever its association with that level —all by means of mantras.
These mantras accomplish the grand acts. But it is the all-pervasive Śiva who has to command these mantras. Who else has authority to command the mantras who lord over even the lords of the lords of gods?
The Ācārya, who has received the Ācāryābhiṣeka — when he calls upon these mantras in his capacity as Śiva himself, they carry out their functions & help the soul realize its innate Śivatva.
So, you just have to “call” those ontological levels & “speak into being” the changes you want at those levels. There are different ways of “making the ontological shake-ups” happen. 6 as the Siddhānta puts it. And 1 of those ways of calling is the way of words – the Padādhva.
