It is good to see this sense of appreciation from participants. When the reality of the 31 realms really sinks in, then it becomes Gratitude, an Infinite measure of it.
See… once one sees the operation of cause and effect, action and reaction (kamma and kamma vipaka) and that that must apply even to the mental world, then it will be natural to accept also the existence of the 31 realms since in the human realm itself we see that causes may have snowball effects – the consequences appearing far too disproportionate to the causes from which they arose. I allude here to cubibobi’s reference to hell. But the ways of Nature cannot be ‘unfair’ – in the long run. Dhammata works that out perfectly well.
As to ‘good births’ above the human, they may be experienced as nicca and sukkha (the Buddha compared the treasures and pleasures even of kings as insignificant therewith) but there is no way of getting around their anatta nature. Death will see to that. So even those good births will count for nothing if one had not gone for Refuge in the Buddha, Dhamma and the Sangha after ‘getting a kick in the rear end’
Everyone seems to want to get a kick out of life these days. Here what one gets is a kick out of many a life of suffering.
