In the tenth verse of his Cidvilāsastava (‘Hymn to the Play of Consciousness’), Amṛtānanda teaches about how the āsana (seat) of the practitioner is to be envisioned as follows:
यत्र निर्विषयबोधलक्षणः स्वात्मशम्भुरवतिष्ठते ऽनिशम् ।
तत्त्वजालकमिदं शिवावधि क्षमामुखं सकलमासनं मतम् ॥ १० ॥
yatra nirviṣayabodhalakṣaṇaḥ svātmaśambhur avatiṣṭhate ‘niśam |
tattvajālakam idaṃ śivāvadhi kṣamāmukhaṃ sakalam āsanaṃ matam || 10 ||
“The “seat” of the practitioner should be understood as that entire collection of reality levels, from earth to Śiva, upon which the deity of the innate Self whose nature is pure awareness is ever established.” (translation by Ben Williams)
