यस्यां समर्च्चयेद्देवं वामनं सिद्धिदं नृणाम् । उपोषितैषा विप्रेंद्र सर्वव्रतफलप्रदा ॥ ११० ॥
yasyāṃ samarccayeddevaṃ vāmanaṃ siddhidaṃ nṛṇām | upoṣitaiṣā vipreṃdra sarvavrataphalapradā || 110 ||

It teaches that focused worship of Lord Vāmana combined with fasting can concentrate the merit of many disciplines into a single observance, making devotion (bhakti) the decisive factor behind ritual fruit.
Bhakti is shown as practical and vow-based: by reverently worshiping Viṣṇu as Vāmana and practicing upavāsa, the devotee attains siddhi and the comprehensive merit associated with multiple vratas.
Ritual discipline (kalpa-oriented practice) is implied: upavāsa (fasting) paired with proper arcana (formal worship) as a structured vrata procedure, emphasizing correct observance rather than technical astrology or grammar.
