The soul eternally seeks Krishna; without Him, all existence feels empty despite worldly abundance.Listen — Srila Prabhupada Uvaca
Prabhupāda: What can young man... What do they understand the aim of life? Educated young men? They are being educated by you.
[indistinct], but they do not know what is the aim of life. What kind of education? Devotee: Śrīla Prabhupāda, I was reading an examination book in Bengal when we were in that small village. And under the psychology section they have one question, “What is the physical basis of consciousness?” This was standard question in Bengal on psychology for high school: “What is the physical basis of consciousness?” So that is what they are asking them. This is exactly... Prabhupāda: Come.
This is a physical question. Aside: [Transl. Come. Come to this side.] The subtlety. bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca [Bg 7.4] Eight: gross and subtle. Mind is subtle matter. Devotee: Śrīla Prabhupāda, how does the subtle mind connect to the gross senses?
Prabhupāda: Mind is the controller of the senses. manaḥ-ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati [Bg 15.7] With mind and the senses, six senses, the living being is struggling in this material world, prakṛti. Everyone is struggling; that is also true. Western theories, struggle for existence. They are struggling, and this is the relief, Kṛṣṇa consciousness.
When he gets Kṛṣṇa consciousness… Just like the other day, the Mathurā meeting, one small child, two years old, was young, and one boy took him on the stage, and his mother came. So how anxiously he went to his mother, happy, steady. He was feeling vacant, all world, without mother. So many people are gathering, but because he could not find out his mother, he was abject.
That is struggle for existence. Everything is there, but he is finding vacant. And that is our position. We are also part and parcel of Kṛṣṇa.
So without Kṛṣṇa the hard struggle for existence is going on. But as soon as he will get Kṛṣṇa, he will be relieved. That is natural, exactly like the child without mother. World, seeing everything vacant; at that stage he cried.
