Mahārāja Parīkṣit had already been advised by his spiritual master, Śukadeva Gosvāmī, to think of the universal form of the Lord, and therefore, following the advice of his spiritual master, he continuously thought of that form. The universal form is certainly material, but because everything is an expansion of the energy of the Supreme Personality of Godhead, ultimately nothing is material. Therefore Parīkṣit Mahārāja’s mind was saturated with spiritual consciousness. Śrīla Rūpa Gosvāmī has stated:
vairāgyaṁ phalgu kathyate
Everything, even that which is material, is connected with the Supreme Personality of Godhead. Therefore everything should be engaged in the service of the Lord. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura translates this verse as follows:
hari-sevāya yāhā haya anukūla
viṣaya baliyā tāhāra tyāge haya bhula
“One should not give up anything connected with the Supreme Personality of Godhead, thinking it material or enjoyable for the material senses.” Even the senses, when purified, are spiritual. When Mahārāja Parīkṣit was thinking of the universal form of the Lord, his mind was certainly situated on the transcendental platform. Therefore although he might not have had any reason to be concerned with detailed information of the universe, he was thinking of it in relationship with the Supreme Lord, and therefore such geographical knowledge was not material but transcendental. Elsewhere in Śrīmad-Bhāgavatam (1.5.20) Nārada Muni has said, idaṁ hi viśvaṁ bhagavān ivetaraḥ: the entire universe is also the Supreme Personality of Godhead, although it appears different from Him. Therefore although Parīkṣit Mahārāja had no need for geographical knowledge of this universe, that knowledge was also spiritual and transcendental because he was thinking of the entire universe as an expansion of the energy of the Lord.
In our preaching work also, we deal with so much property and money and so many books bought and sold, but because these dealings all pertain to the Kṛṣṇa consciousness movement, they should never be considered material. That one is absorbed in thoughts of such management does not mean that he is outside of Kṛṣṇa consciousness. If one rigidly observes the regulative principle of chanting sixteen rounds of the mahā-mantra every day, his dealings with the material world for the sake of spreading the Kṛṣṇa consciousness movement are not different from the spiritual cultivation of Kṛṣṇa consciousness.
