Varṣa-devatā Worship in Jambūdvīpa: Hayagrīva/Hayaśīrṣa, Nṛsiṁha, Kāmadeva (Pradyumna), Matsya, Kūrma, and Varāha
उत्तरेषु च कुरुषु भगवान् यज्ञपुरुष: कृतवराहरूप आस्ते तं तु देवी हैषा भू: सह कुरुभिरस्खलितभक्तियोगेनोपधावति इमां च परमामुपनिषदमावर्तयति ॥ ३४ ॥
uttareṣu ca kuruṣu bhagavān yajña-puruṣaḥ kṛta-varāha-rūpa āste taṁ tu devī haiṣā bhūḥ saha kurubhir askhalita-bhakti-yogenopadhāvati imāṁ ca paramām upaniṣadam āvartayati.
Śukadeva Gosvāmī said: Dear King, the Supreme Lord in His boar incarnation, who accepts all sacrificial offerings, lives in the northern part of Jambūdvīpa. There, in the tract of land known as Uttarakuru-varṣa, mother earth and all the other inhabitants worship Him with unfailing devotional service by repeatedly chanting the following Upaniṣadic mantra.
It states that the Supreme Lord, as Yajña-puruṣa, resides among the northern Kurus in the form of Varāha, and is worshiped there by Bhū-devī and the Kurus with unwavering bhakti.
Because He is the true Lord and enjoyer of all sacrifices; the verse emphasizes that devotion to Him is the essential purpose behind yajña.
Maintain steady devotional practice—regular prayer/chanting, remembrance of the Lord, and consistent service—without giving up due to distractions or changing circumstances.
