विघ्नेशो मातरो दुर्गा क्षेत्रज्ञो देवता दिशः आग्नेयादिषु कोणेषु चतुर्ष्वपि यथाक्रमम्
vighneśo mātaro durgā kṣetrajño devatā diśaḥ āgneyādiṣu koṇeṣu caturṣvapi yathākramam
Dans les quatre directions d’angle, en commençant par le sud-est, qu’on établisse (invoque) selon l’ordre : Vighneśa, les Mères (Mātṛkās), Durgā, puis le Kṣetrajña — la divinité présidant aux directions — afin que les quartiers soient sanctifiés pour le culte du liṅga de Śiva.
Suta Goswami (narrating Shiva-puja vidhi to the sages of Naimisharanya)
It prescribes the protective and purificatory placement of deities in the four corner-directions, removing obstacles (Vighneśa) and establishing śakti-guardians (Mātṛkās, Durgā) so the ritual-field (kṣetra) becomes fit for Śiva’s liṅga-archanā.
Śiva-tattva is implied as the central Pati (Lord) whose worship requires a consecrated kṣetra; the directions and śaktis are harmonized around him, showing Śiva as the axis of order while Śakti and guardians regulate the manifest field.
A puja-vidhi step akin to dik-bandhana/kshetra-raksha: invoking corner deities to secure the ritual space before liṅga-pūjā, japa, or Pāśupata-oriented sādhana.
