आप्यं द्रवमिति प्रोक्तं वर्णाख्यो वह्निरुच्यते यत्संचरति तद्वायुः सुषिरं यद्द्विजोत्तमाः

水被宣说为“流动性”的原则;火被称为显现色与形之者。凡能运行者名为风;凡中空者——噢最胜的二生者——即为虚空(ākāśa)。
Suta Goswami (narrating a tattva-teaching within the Linga Purana discourse)
It identifies the defining marks (lakṣaṇas) of the elements, supporting bhūta-śuddhi and pañcabhūta contemplation used to purify the devotee’s body-mind before Linga-pūjā, so the Pashu approaches Pati with reduced pāśa (bondage).
By classifying water, fire, wind, and space through their functions, it implies that these bhūtas are knowable effects within prakṛti, while Shiva as Pati is the transcendent ground that illumines and governs them without being limited by their properties.
Bhūta-viveka and bhūta-śuddhi (elemental discernment and purification), a Pāśupata-aligned preparatory discipline for mantra-japa, prāṇāyāma, and focused Linga-upāsanā.
