रसाणों बुधमन्त्रोऽयं मुनिब्रह्मास्य कीर्तितः । पंक्तिश्छैदो देवता तु बुधः सर्वेष्टदो नृणाम् ॥ १२२ ॥
rasāṇoṃ budhamantro'yaṃ munibrahmāsya kīrtitaḥ | paṃktiśchaido devatā tu budhaḥ sarveṣṭado nṛṇām || 122 ||
Voici le mantra de Budha (Mercure) ; il est dit que son ṛṣi, parmi les sages, est Brahmā. Son mètre est Paṅkti, et sa divinité présidante est Budha, qui accorde aux hommes l’accomplissement de tous les souhaits.
Narada (teaching in a Vedanga/Jyotisha-oriented context, as preserved in the Narada Purana dialogue tradition)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It formally defines the mantra’s traditional identifiers—seer (Brahmā), metre (Paṅkti), and deity (Budha)—showing that mantra-practice is anchored in Vedic parameters (ṛṣi–chandas–devatā) rather than mere recitation.
While the verse is technical (Jyotisha/mantra-lakṣaṇa), it still frames practice as devotion to a presiding deity—Budha—through mantra, implying disciplined worship (upāsanā) aimed at righteous fulfillment of human goals.
It highlights Vedāṅga usage—especially Chandas (metre) and Jyotiṣa-style mantra classification—by specifying the mantra’s chandas (Paṅkti) and devatā (Budha), which are essential for correct viniyoga (application) in ritual practice.
