Prākṛta-pralaya, Pratisarga Doctrine, and the Ishvara-Samanvaya of Yoga and Devotion
ज्ञानं तदुक्तं निर्बोजं पूर्वं हि भवतां मया / विष्णुं रुद्रं विरञ्चिं च सबीजं भावयेद् बुधः / सथवाग्न्यादिकान् देवांस्तत्परः संयतेन्द्रियः
jñānaṃ taduktaṃ nirbojaṃ pūrvaṃ hi bhavatāṃ mayā / viṣṇuṃ rudraṃ virañciṃ ca sabījaṃ bhāvayed budhaḥ / sathavāgnyādikān devāṃstatparaḥ saṃyatendriyaḥ
先に汝らに「無種子」（nirbīja）として説いたその智は、まことにすでに教えられた。されど賢き求道者は、諸根を制し彼なる真実に専心して、「有種子」（sabīja）としてヴィシュヌ、ルドラ、ヴィランチ（ブラフマー）を、またアグニに始まる諸 देव（神々）をも、禅定の依りどころとして観想すべきである。

FAQs
It distinguishes “nirbīja” knowledge—absorption without any support-object—from “sabīja” contemplation, implying that the Supreme can be realized beyond forms, while forms can still serve as preparatory supports.
It explicitly teaches two modes: nirbīja (supportless) realization and sabīja (supported) dhyāna, where the practitioner uses divine forms—Viṣṇu, Rudra, Brahmā, and other devas like Agni—as ālambana while restraining the senses.
By prescribing meditation on Viṣṇu and Rudra together as valid supports, it reflects the Kurma Purana’s synthetic, non-sectarian stance where Śaiva and Vaiṣṇava forms function harmoniously within one path toward the Supreme.
