It seems to me that things in this world come in waves. They start, they build, they peak and they fade. Where is the sunset at noon? Where is the sunset at midnight? The potential is there all the time but the components take a different form and we don't see the delightful gold, pink and green in those forms at that time.
Similarly, we know that the baby will talk and run later. Just after birth, its muscles and nerves are in an arrangement that does not include speech and full motion yet. All the while things are coming and going, waxing and waning, we are living our lives, observing, remembering, loving, suffering, thinking. Some of peaks and valleys of experiences and development please us and some don't.
Some moments of development are so fulfilling that we want them to stay still. We want to stay in those states of falling in love, winning the game, making the sale. Some traditions of Buddhism talk about the Hungry Ghosts, creatures who are hungry but cannot eat, cannot be satisfied. Life is constantly rising and falling and contentment for us is temporary. If she accepts my marriage proposal, my rival fails. If we win the game, they will not feel contented.
I really like talking to my mom. At a very early age, I couldn't talk and neither of us expected it. For a long time, though, I was in a form and she was in a form that did allow us good talk. After her death and cremation, her existence changed into a state where she can't talk. Her atoms are still around but in her present form, I get less satisfaction from talk with her. She is not now in a talking form. I remember when she was but she isn't now.
