षडध्व-शुद्धिः
Purification of the Six Adhvans / Sixfold Cosmic Path
नम आद्यैर्यकरांतैः कल्पयेत्कल्पवित्तमः । ईशानं मध्यमे कुंभे पुरुषं पुरतः स्थिते
nama ādyairyakarāṃtaiḥ kalpayetkalpavittamaḥ | īśānaṃ madhyame kuṃbhe puruṣaṃ purataḥ sthite
次に、儀礼の配列に通じた行者は、「na」に始まり「ya」に終わる真言の字母を心中に安置すべきである。中央のクンバ(kumbha)にはイーシャーナ(Īśāna、シヴァ)を観想し、前に置かれた器にはプルシャ(Puruṣa)—主の浄化の相—を観想すべきである。

Tattva Level: pati
Shiva Form: Īśāna
Mantra: na … ya (i.e., the pañcākṣarī sequence: na-ma-śi-vā-ya)
Type: panchakshara
It teaches mantra-śuddhi through deliberate mental construction (kalpanā/nyāsa): the practitioner installs Śiva’s aspects in ritual supports, turning external worship into an inward concentration on Pati (Śiva) as the liberating Lord.
By assigning Īśāna and Puruṣa to specific ritual vessels, the worshipper approaches Saguna Śiva through form-supported contemplation, a preparatory means that steadies the mind for realizing Śiva’s transcendent nature.
Mantra-nyāsa/visualization of the Pañcākṣarī sequence (na…ya) with kumbha-upacāra: contemplate Īśāna in the central kumbha and Puruṣa in the front vessel as part of focused Śiva-upāsanā.
