In Celtic history the stones are the Elderly and the wisest. They hear and see everything. It is not said they do not feel because they do not express, although if you hold them they feel warm or cold, smooth or hard. The same counts for trees. They feel, plants feel pain and respond. If you talk to them they grow, even if it is only a few words. Trees get cancer from people, radiation... There are also tree huggers. Darío is wrong. For sure he is not one with nature and not high sensible.

This for sure is right to a very big group, not everyone:

for there is no pain greater than the
pain of being alive,
nor a heavier burden than conscious life.

And if comes to these words:

Life is also about living it as it comes. Loving oneself first and foremost. Nothing lasts forever; pain passes, and love passes.

In a constructed world where everyone is forced to live according to the rules and if not filthy rich there's no way to take life as it comes, you are punished if you show the slightest way of selfishness, will be scolded, abused, beaten up.

Trust me pain lasts forever. It doesn't pass, will not be forgotten.
Some might get out while others sink, or are kicked, deeper and deeper into the swamp, with help of those few they thought would be close family or friends since there love wasn't there at the first place.

True love exists, but is fought in this world most by family, relatives and friends/society.
