सगुणो निर्गुणो वापि तस्याज्ञां शिरसा वहेत् श्रेयो ऽर्थी यस्तु गुर्वाज्ञां मनसापि न लङ्घयेत्
saguṇo nirguṇo vāpi tasyājñāṃ śirasā vahet śreyo 'rthī yastu gurvājñāṃ manasāpi na laṅghayet
无论观想主为有相具德(saguṇa),或超越诸德无相(nirguṇa),都应将祂的命令顶戴于首。求至上善者,切莫违越上师之教令——即使在心念之中亦不可。
Suta Goswami (narrating a doctrinal instruction within the Purva-Bhaga teaching sequence)
It frames Linga-upāsanā as a discipline rooted in ājñā (injunction): the devotee (pashu) progresses toward śreyas by honoring Shiva’s and the Guru’s command with total reverence, making ritual and conduct aligned with Śaiva dharma.
It allows both saguna and nirguna contemplation: Shiva as Pati can be worshiped with form and qualities for devotion, yet realized as beyond all guṇas in the highest insight—without contradiction.
Guru-ājñā-anusaraṇa (strict adherence to the Guru’s instruction) is emphasized as a core Pāśupata discipline—purifying the mind so that worship and yoga are not broken even at the level of intention.
