The soul pilots the body machine to higher or lower realms based on consciousness; Krishna Consciousness exposes all false knowledge.Listen — Srila Prabhupada Uvaca
Prabhupāda: ...the Lord then said, [Transl. The Supreme Lord has answered it.] This... [break] Puṣṭa Kṛṣṇa: Mamaivāṁśo jīva-loke jīva-bhūtaḥ sanātanaḥ [Bg 15.7]. Gurukṛpā: "The living entities in this conditional world are My eternal, fragmental parts.
Due to conditioned life, they are struggling very hard with the six senses, which include the mind." Prabhupāda: So with this instrument he's manipulating this machine, as exactly the pilot, with so many electronics, machine, he's working the flying of the plane. Where is the difficulty to understand? And this is..., body is a machine. Bhrāmayan sarva-bhū...
[Bg 18.61]. Bhrāmayan, wandering. The aeroplane is wandering. This machine is wandering.
It is also going, ūrdhvaṁ gacchanti sattva-sthāḥ, sometimes up, sometimes down. Huh? Find out this. [discussion as devotees look for verse] Same aeroplane, going up and down.
Two wings, this hand, like this. Gurukṛpā: ūrdhvaṁ gacchanti sattva-sthā madhye tiṣṭhanti rājasāḥ jaghanya-guṇa-vṛtti-sthā adho gacchanti tāmasāḥ [Bg 14.18] "Those situated in the mode of goodness gradually go upward to the higher planets; those in the mode of passion live on the earthly planets; and those in the mode of ignorance go down to the hellish worlds." Prabhupāda: So same thing: if the pilot is not expert, then goes down to the nose, finished. Adho gacchanti tāmasāḥ. If the pilot is third class, instead of going up, he goes down, and everything is spoiled.
So everything on the pilot. The machine is not important. The machine can go up if the pilot knows how to do it. And the machine can go down.
Actually, it is happening. This landing point is very dangerous. If the pilot cannot handle very nicely, immediately smashed. The crash takes place while going up and coming down, generally.
