على المرأة الحائض أن تمتنع، بكلّ احتياط، عن أفعال التحية بالتعظيم (النمسكار)؛ وعليها أيضًا أن تتجنّب لمسَ امرأةٍ حائض أو محادثتها.
Suta Goswami (narrating Śaiva dharma-ācāra to the sages of Naimiṣāraṇya)
It frames śauca (ritual purity) as a supportive discipline for Śiva-pūjā—advising temporary restraint in certain social-ritual acts so that worship is performed with regulated conduct (ācāra) and undisturbed observance.
Implicitly, it treats Śiva as Pati—ever pure and transcendent—while prescribing purity-based disciplines for the pashu (individual practitioner) bound by pasha (bodily and ritual conditions), emphasizing regulated approach rather than any limitation in Śiva.
A śauca-ācāra rule within Śaiva pūjā-vidhi: during rajas (menstruation), one should avoid formal namaskāra and avoid contact/conversation with another rajasvalā, as part of observance-based discipline rather than an internal yogic technique.
