The wheel goes round and round and round forever. Pleasure, pain, birth and death, lifetime after lifetime, it is endless. All sentient beings experience this, the endless dance of life, the lila.
You have but a short time to live in this world. As you age, you will experience the pains of aging. If your hopes and joys rest upon the body, then you will suffer greatly.
At the end of your life you will probably end up in an old-age home, or in a back room in one of your children's houses, left only with a handful of fading memories and a body racked with great pain and suffering.
We fall into states of illusion - we forget all this. We get caught up in desires, frustrations, political movements, philosophies, religions, the getting of a living, the pain of a body, the pleasure of a body.
When you are enlightened, your physical body will still feel pain if you get hurt, but you will not be overwhelmed even by extreme physical pain, because your mind is filled with light, love and understanding.
You have no fixed self. This is only an illusion that causes you to feel pain and suffering.
Being on the path means we again meditate with joy. We deal with the suffering of life and the pain of existence without perfect enlightenment with a smile.
There's really no pain in the realm of the higher astral. A lot of spirits are playing mini-golf having a good time.
