उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
न्यस्यते यत्तदुत्पत्तिर् विपरीतं तु संहृतिः अङ्गुष्ठादिकनिष्ठान्तं न्यस्यते हस्तयोर् द्वयोः
nyasyate yattadutpattir viparītaṃ tu saṃhṛtiḥ aṅguṣṭhādikaniṣṭhāntaṃ nyasyate hastayor dvayoḥ
Lo que se coloca mediante nyāsa en el orden directo significa utpatti (emanación, despliegue creador del Señor); y el orden inverso significa saṃhṛti (retiro, reabsorción). Desde el pulgar hasta el meñique, el nyāsa debe realizarse en ambas manos.
Suta Goswami (narrating Linga-puja and nyasa procedure to the sages of Naimisharanya)
It defines how kara-nyāsa (hand-nyāsa) encodes Shiva’s cosmic functions: forward placement mirrors creation (utpatti) and reverse placement mirrors dissolution (saṃhṛti), making the worshipper’s hands fit instruments for Linga-puja.
Shiva-tattva is implied as Pati, the Lord who manifests and withdraws the cosmos; nyāsa ritually aligns the practitioner with these powers, pointing to Shiva as both the source and the reabsorbing ground of all tattvas.
Kara-nyāsa: installing mantra-power on the fingers of both hands, in forward or reverse order, as a preparatory discipline for japa and Linga-puja—an internalizing step consistent with Pāśupata-oriented ritual yoga.
