The verse catalogs specialized vidyās (knowledge-systems) that support dharma—especially mantra-practice, correct phonetics/letters (mātṛkā), and form-based worship (mūrti)—showing that spiritual life is aided by precise auxiliary sciences.
By including 'Mūrti' and 'Mātṛkā', it implies bhakti is strengthened through correct mantra-recitation (sound/letters) and proper icon/form understanding, aligning worship with śāstra rather than mere sentiment.
The emphasis on Mātṛkā points to śikṣā/phonetics and the discipline of correct sound-units used in mantra, while the other named vidyās indicate applied śāstras (classification of principles, forms, and specialized teachings).
