Earth, 114 million years ago, one morning just after sunrise: The first flower ever to appear on the planet opens up to receive the rays of the sun. Prior to this momentous event that heralds an evolutionary transformation in the life of plants, the planet had already been covered in vegetation for millions of years. The first flower probably did not survive for long, and flowers must have remained rare and isolated phenomena, since conditions were most likely not yet favourable for a widespread flowering to occur. One day, however, a critical threshold was reached, and suddenly there would have been an explosion of colour and scent all over the planet - if a perceiving consciousness had been there to witness it. Much later, those delicate and fragrant beings we call flowers would come to play an essential part in the evolution of consciousness of another species. -- A New Earth, Eckhart Tolle.
I think this perfectly describes what it means to be a parent. It is to create the conditions necessary to help a little flower blossom and fill this world with colour and fragrance.
