here is a semi-interesting question ))))))), we talked about the origins of karma (http://www.dharmawheel.net/viewtopic.php?f=77&t=18669) excellent comments there, thank you! ...now let's talk about the related topic of the history of samsara on earth... let's focus on the animal realm in particular -- but all realms of suffering are included in this topic. http://en.wikipedia.org/wiki/Timeline_o ... ry_of_life question: did samsara on earth begin 570 million years ago?
the first animal life on earth was probably a sponge and probably 570 million years ago. was that the beginning of suffering on earth? or were the microbes (single cell life 3.6 billion years ago) and simple multi-cell organisms (1 billion years ago) opening the doors of samasara for animal life on planet earth? or is the evolution of animal life on earth irrelevant because the hell realm, hungry ghost realm, anti-god realm and god realm have been here on planet earth since its initial formation 4 billion years ago?
his holiness the dalai lama wrote in "the four noble truths, the truth of suffering" 1996, pg 83:
i will put forward my answer from the start. openeing my mind/heart to disernment/snang-ba mtha'-yas/amitabha, i would say that samsara is more subtle, a feeling. it is the unrequited desire, the unstable and unrealistic highs of satiation, then on a more subtle level it is the heart ache that comes with change juxtaposed with the idea of self. so i say that samsara started on earth with life on earth which started 3.6 billion years ago. buddhists believe that plants don't have feelings and early microbes were much like plants. but we are not talking about feelings we are talking about samsara and i feel in my heart that there are clear signs on samsara in plant life, no question. look in 1 sq foot of your lawn how each plant tries to take the sun from the next plant, tries to extend its roots and take the nourishment from other plants, this is a struggle and with it comes suffering.At what point does karma play a casual role in producing sentient beings and the natural environment in which they live? Perhaps we can say that there is a natural process in the world, and at a certain point when its evolution has reached a stage where it can affect the experiences of beings - giving rise to either painful experiences of suffering or joyful experiences of happiness - that is the point where karma enters the picture.
