Prabhupada: Today's subject matter is life after death. So we
shall try to speak something on this subject. So life after death
is not very difficult to understand. We have got different grades
of life. Just like the child is crying, that is also life. Then
the child body vanquished then gets another body, boy's body.
Then this body also vanquishes. Another body, youthful body. This
body also vanquishes. And then an old man's body like me, this
will also vanquish. So the logic is as the other bodies vanquish
and I get a next body, similarly, when this old body will be
vanquished, I'll get another body. So here it is stated by the
supreme authority Krsna, that as these bodies are changing in
this duration of life... It is changing. The old body, the
child's body, boy's body of me, they are no longer existing, but
I am existing. I know that I had a small body like this. I had a
boy's body, youthful body. I can remember. Therefore I am
eternal. The bodies are temporary. So this is evolution. This
evolution theory... It is not theory; it is fact, stated in the
Vedic literature, Padma Purana, how we have passed through so
many bodies, and ultimately we have got this civilized, human
form of body. We have to pass through 900,000 forms of aquatic
bodies within the water. Then, gradually, we come to the form of
trees and plants. There are two million varieties. Then we get
the bodies of the insect. There are 900,000 forms of body. Then
we enter into the species of birds, one million forms of body.
Then, after bird's body, there are three million different
varieties of beast body. Then, after this period, we become human
body, but there are 400,000 species of human body. And thus we
get this nice human form of body with good brain and good
consciousness. So it should be utilized properly. That... By the
laws of nature, prakrteh kriyamanani gunaih karmani sarvasah.
This is the law of nature. Gradually we develop different types
of body and different types of consciousness. So when we come
finally to God consciousness, or Krsna consciousness, that is the
perfection of life. So we are living in this planet, but in other
planets also, there are different forms of life. So there is one
planet... There are many millions of planets. Specifically, there
is one planet within this universe, that is called Siddhaloka.
There is other planet also, heavenly planet, Brahmaloka planet.
And in different planets there are different species of life,
different standard of comforts. But in the higher planetary
system, the standard of comfort is more and more, thousand times
more, thousand times more, in this way. Just like in this planet
we have got different standard of life. In your western
countries, your standard of life is, at least, it is to be
understood more comfortable than other standard of life. In this
way, if you promote yourself to the topmost planetary system,
which is called Brahmaloka, then you get your duration of life
many millions of years. It is stated in the Bhagavad-gita that
sahasra-yuga-paryantam arhad yad brahmano viduh. In the
Brahmaloka planet, the residents, they have got their one day.
One day means day time. Not night time. Twelve hours, say. That
is equal to, their twelve hours is equal to our millions of
years. Sahasra-yuga. Sahasra-yuga means 43 hundred thousands of
years multiplied by one thousand. That is called sahasra-yuga.
Such is the, such duration of time is equal to twelve hours in
the Brahmaloka planet. So even if you go to the Brahmaloka
planet... So our natural tendency is to go to other, better
planets. Therefore people are trying to go to the moon planet.
Similarly, you can go to the sun planet, heavenly planet. There
are so many. But the information is, even though you reach the
topmost planet of this universe, still, there the four principles
of material life, namely, birth, death, old age and disease, are
there. So we can go to the topmost planet. There is process how
to go. Urdhvam gacchanti sattva-stha madhye tisthanti rajasah,
jaghanya-guna-vrtti-stha adho gacchanti tamasah. If you keep
yourself in sattva-guna or in the modes of goodness, you are
promoted to the higher planetary system. Even to the topmost
planetary system. That is called urdhvam gacchanti sattva-stha.
And if you keep yourself in the modes of passion, you shall
remain within the middle planetary system. This is middle
