Adhyaya 84: शिवव्रतकथनम्
Uma–Maheshvara Vrata, Shula-dana, and Month-wise Ekabhakta Vrata
लभते नात्र संदेहः सत्यं सत्यं वदाम्यहम् कार्तिक्यां वा तु या नारी एकभक्तेन वर्तते
labhate nātra saṃdehaḥ satyaṃ satyaṃ vadāmyaham kārtikyāṃ vā tu yā nārī ekabhaktena vartate
她必定获得所许之果,毫无疑惑。我真实、真实地宣说:凡女子于迦尔提迦月(Kārttika)以一心专敬(ekabhakti)奉事主宰帕提(Pati)者,皆蒙赐此恩。
Suta Goswami (narrating to the sages of Naimisharanya; conveying the phala-shruti of Kartika observance in a Shaiva frame)
It functions as a phala-shruti: during Kārttika, single-minded devotion to Shiva (often expressed through Linga-puja and vrata) is affirmed as certainly fruitful, emphasizing anugraha (Shiva’s grace) as the decisive factor.
By stressing certainty and “truth upon truth,” the verse highlights Shiva as Pati who grants assured results to the pashu when devotion becomes one-pointed—grace is not random but responds to steadfast inner orientation.
Kartika-vrata anchored in ekabhakti—practically, steady daily worship and disciplined conduct; yogically, ekāgratā (one-pointedness) that loosens pāśa (bondage) and turns the soul toward Pati.
