Brahman realization alone is incomplete; only devotional service to Krishna achieves supreme spiritual perfection.Listen — Srila Prabhupada Uvaca
interference] In the Bhagavad-gītā you'll find, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati [Bg. 18.61]. Īśvaraḥ, the Supreme Lord, is residing in everyone's heart. Sarva-kṣetreṣu. Ksetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata [Bg. 13.3]. [O scion of Bharata, you should understand that I am also the knower in all bodies, and to understand this body and its owner is called knowledge. That is My opinion.] In Bhagavad-gītā you'll find, kṣetra-kṣetrajña: the self and this body.
And Bhagavad-gītā is stating what is this body and what is the self. So in that connection the Lord says that "You, the individual soul, he's the proprietor of this body." Or not exactly proprietor, but leaseholder. You cannot say you are proprietor, because as soon as you'll be asked, "Vacate," oh, you have to vacate. But you can say "leaseholder." Actually, it is leaseholder.
We are, we are holding this body on certain lease term, for so many years. As soon as the lease period is over, "Vacate. Please vacate." "Oh, I have got so much attraction for this body. How can I vacate?" Oh, there is no argument.
"Please vacate, immediately." "Oh, I am president of USA." "Oh, never mind. Immediately." [laughter] Yes, immediately. So don't you see? So what is use of becoming president?
If I am so much under the laws of nature, under the order of Supreme, that immediately I am going in procession very nice, and then, oh, there is shot and finished everything... Therefore those who are sensible, they do not aspire for all these temporary things. Temporary bodily acquisitions: good birth, good opulence, good beauty and good knowledge—these are bodily acquisitions. Everyone is very much proud if he's born in a nice family or nice nation. Oh, he's very proud, "I am Englishman," or "American," "I am this," "I am brāhmaṇa," "I am this, [indistinct] proud." Why?
Good birth. Then, if one is very rich, oh, he's very proud. Then, if one is very much learned, he is very proud. And if one is very beautiful, he's also very proud.
Janmaiśvarya-śruta-śrībhiḥ [SB 1.8.26]. [My Lord, Your Lordship can easily be approached, but only by those who are materially exhausted, because one who is on the path of [material] progress, trying to improve himself with respectable parentage, great opulence, high education and bodily beauty, cannot address You with sincere feeling.] These are our objects of being proud. But this can be finished within a second, because it is due to this body. So actually, those who are in the bodily concept of life, they're in the lower grade of human civilization. Just like animals. They are considered as animals.
