It teaches that tattva-nyāsa (ritual installation of cosmic principles upon oneself) is a means to stabilize dhiṣṇu-bhāva—deep identification and absorption in Viṣṇu—using an anciently transmitted eight-syllabled mantra.
Bhakti here is made practical: devotion is cultivated not only by emotion but by disciplined upāsanā—nyāsa and mantra-japa—so the devotee’s body-mind becomes aligned with Viṣṇu-consciousness (dhiṣṇu-bhāva).
It highlights technical ritual method (prayoga) involving mantra structure (aṣṭākṣarī) and nyāsa—knowledge aligned with Vedāṅga-style precision in recitation/application and the procedural sciences used in worship.
