Rakshasa wrote:Suppose someone is greedy and filthy rich in this life and looks down upon the poor, and because of accumulation of bad Karma, he gets a rebirth in abject poverty condition. But poor people become humble and less greedy because of their experiences. So because of his next life's experiences and actions as a very poor peasant, the man gains good qualities and again regains good Karmic roots - which give him a birth as a rich man again in the next life. This goes on again and again? I hope, despite my lack of good articulation, most of you understood where I am pointing at.
Not necessarily, a poor peasant can also be greedy and ambitious and willing to get rich at the expense of his fellow peasants and a rich man can be generous with their wealth. You seem to be linking karma to fate, you forget the matter of choce involved in ones actions (as a human being).
If someone has done great offenses, broken the precepts and become a hungry ghost in this life, because of immense suffering he will become more compassionate with greater solidarity with other hungry ghosts. Which means, his birth in a higher realm is assured due to his experiences in hell.
Again this is untrue. Consider the story of the Buddha and the thief:
The Spider Thread
(from a lecture by Masao Yokota)
The Buddha was in a lotus-filled garden when he perceived a man named “Kandata” who was squirming in the depths of Hell. He had been a murderer, an arsonist, and thief. A lifetime of these causes had put him in hell. He was in the company of others like him.
The Buddha looked further into Kandata’s life and saw an incident where Kandata came upon a spider. He raised his foot to stomp on it. Suddenly, he reconsidered, thinking, "There is no doubt that this spider is also a living being and it is a shame to take its life for no reason." In the end he spared the spider.
Knowing this, the Buddha took a spider thread and lowered it to into depths of Hell with the intention of saving Kandata.
Kandata reached for the thread and found it strong enough to hold his weight. Using all his strength he began lifting himself from Hell.
After some progress, he looked down and saw hundreds of others behind him climbing on the same spider thread.
He shouted back at them: “Get off! This is mine!” Just then, the thread broke and Kandata fell back into Hell.
There is nothing in Buddhism that says that suffering is redemptive. Samsara is suffering. This suffering is neither redemptive nor a punishment.
which means all animals have a higher birth assured in future?
Nope. Positive or wholesome actions assure higher rebirths and/or liberation not birth in the animal realm. Rebirths in lower realms are consequences not causes. It is, of course, very difficult to accumulate positive causes whilst in the lower states (and in the God realms). That is the importance of human rebirth, we have a chice as to whether we will accumulate merit through our actions or just keep the cycle going.
So can we conclude that the cyclical existence is not only cyclical in the sense of "birth and rebirth" but also in the sense of circling in different states and realms again and again?
Yes and no. You can (right now) take advantage of your precious human birth and break the cycle forever.
