SRIMAD-BHAGAVATAM 9 CHAPTER 9 TEXT 46
ye vikṣiptendriya-dhiyo
devās te sva-hṛdi sthitam
na vindanti priyaṁ śaśvad
ātmānaṁ kim utāpare
TRANSLATION
Even though the demigods have the advantages of being situated in the higher planetary system, their minds, senses and intelligence are agitated by material conditions. Therefore, even such elevated persons fail to realize the Supreme Personality of Godhead, who is eternally situated in the core of the heart. What then is to be said of others, such as human beings, who have fewer advantages?
PURPORT
It is a fact that the Supreme Personality of Godhead is always situated in everyone’s heart (īśvaraḥ sarva-bhūtānāṁ hṛd-deśe ’rjuna tiṣṭhati [Bg. 18.61]). But because of our material anxieties, which are inevitable in this material world, we cannot understand the Supreme Lord, although He is situated so near to us. For those always agitated by material conditions, the yogic process is recommended so that one may concentrate his mind upon the Supreme Personality of Godhead within the heart. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ [SB 12.13.1]. Because in material conditions the mind and senses are always agitated, by the yogic procedures like dhāraṇā, āsana and dhyāna one must quiet the mind and concentrate it upon the Supreme Personality of Godhead. In other words, the yogic process is a material attempt to realize the Lord, whereas bhakti, devotional service, is the spiritual process by which to realize Him. Mahārāja Khaṭvāṅga accepted the spiritual path, and therefore he was no longer interested in anything material. Kṛṣṇa says in Bhagavad-gītā (18.55), bhaktyā mām abhijānāti: “Only by devotional service can I be understood.” One can understand Kṛṣṇa, the Parabrahman, the Supreme Personality of Godhead, only through devotional service. The Lord never says that one can understand Him by performing mystic yoga or by philosophically speculating. Bhakti is above all such material attempts. Anyābhilāṣitā-śūnyaṁ jnāna-karmādy-anāvṛtam [Bhakti-rasāmṛta-sindhu 1.1.11]. Bhakti is uncontaminated, being unalloyed even by jnāna or pious activities.
