The Advent of Lord Krṣṇa: Introduction

of this when it clearly says,  yogamāyām upāśritaḥ . On the other hand, there were  asuras  headed by Śālva and  kṣatriyas  like Duryodhana who were bereft of devotional service in spite of seeing Krṣṇa's carrier Garuḍa and the universal form, and who could not understand Krṣṇa to be the Supreme Personality of Godhead. This was also bewilderment, but this bewilderment was due to  mahāmāyā . Therefore it is to be concluded that the  māyā  which drags a person from the Supreme Personality of Godhead is called  jaḍamāyā , and the  māyā  which acts on the transcendental platform is called  yogamāyā . When Nanda Mahārāja was taken away by Varuṇa, he saw Krṣṇa's opulence, but nonetheless he thought of Krṣṇa as his son. Such feelings of parental love in the spiritual world are acts of  yogamāyā , not of  jaḍamāyā , or  mahāmāyā . This is the opinion of Śrīla Viśvanātha Cakravartī Thākura.
Śūrasenāṁś ca.  The son of Kārtavīryārjuna was Śūrasena, and the countries he ruled were also called Śūrasena. This is noted by Sanātana Gosvāmī in his  Vaiṣṇava-toṣaṇī  commentary.
In regard to Mathurā, we find this quotation:
mathyate tu jagat sarvaṁ brahma-jñānena yena vā tat-sāra-bhūtaṁ yad yasyāṁ mathurā sā nigadyate
When a self-realized soul acts in his transcendental position, his situation is called Mathurā. In other words, when one acts in the process of  bhakti-yoga , he may live anywhere, but actually he lives in Mathurā, Vrṇdāvana. Devotion to Krṣṇa, the son of Nanda Mahārāja, is the essence of all knowledge, and wherever such knowledge is manifested is called Mathurā. Also, when one establishes  bhakti-yoga , excluding all other methods, one's situation is called Mathurā.  Yatra nityaṁ sannihito hariḥ : the place where Hari, the Supreme Personality of Godhead, lives eternally is called Mathurā. The word  nitya  indicates eternality. The Supreme Lord is eternal, and His abode is also eternal.  Goloka eva nivasaty akhilātma-bhūtaḥ . Although the Lord is always stationed in His abode, Goloka Vrṇdāvana, He is present everywhere in fullness. This means that when the Supreme Lord descends on the surface of the world, His original abode is not vacant, for He can remain in His original abode
