Adhyaya 84: शिवव्रतकथनम्
Uma–Maheshvara Vrata, Shula-dana, and Month-wise Ekabhakta Vrata
सा च सार्धं महादेव्या मोदते नात्र संशयः चैत्रे भवं कुमारं च भवानीं च यथाविधि
sā ca sārdhaṃ mahādevyā modate nātra saṃśayaḥ caitre bhavaṃ kumāraṃ ca bhavānīṃ ca yathāvidhi
彼女(礼拝者)はマハーデーヴィーとともに歓喜する――疑いはない。チャイトラ月には、定められた作法により、バヴァ(シヴァ)、クマーラ(スカンダ)、そしてバヴァーニー(聖なる母)を礼拝すべきである。
Suta Goswami (narrating the observance/puja-vidhi to the sages of Naimisharanya)
It links ritual correctness (yathāvidhi) with devotional fruition: by worshipping Bhava with Śakti (Bhavānī) and their divine son (Kumāra) in Caitra, the devotee attains auspiciousness and delight in the presence of the Goddess—an implicit affirmation that Linga-oriented worship culminates in Shiva-Shakti grace.
Śiva is invoked as Bhava—the Pati (Lord) whose worship, when united with Śakti (Mahādevī/Bhavānī), yields immediate spiritual joy and certainty of result (“nātra saṃśayaḥ”), reflecting Shiva-tattva as the sure refuge that loosens pāśa (bondage) for the pashu (soul) through divine grace.
A calendar-based vrata/pujā practice is indicated: in Caitra, perform worship of Bhava, Kumāra, and Bhavānī according to injunctions (yathāvidhi). The yogic takeaway is disciplined observance (niyama) expressed as regulated worship that aligns the pashu toward Pati through śakti-anugraha (grace).
