The main substance of life in human history has been sustainable agriculture. Humans have learned through the evolution of life how to gather and plant seeds. It is said that women were the first to gather the seeds from different plants and notice their growth and uses. Through generations mothers and fathers shared the knowledge to continue the nutrition of our substenance.

Natives of all four corners of our sacred earth, the yellow, white, black and red peoples used differrent techniques, practices, crops, fertilizer, and watering methods.The results may have been a bit different but the purpose was the same, to produce food by using all available means of natural resources in the environment.  

With keen observation to the universe, watersheds, rising and setting of the sun, the cycles of the moon, type of soils, or land structure, companion planting, animals, insects and all that envelopes the creation of life a cosmovision was realized knowing that life is a complete circle that changes as it moves within space. They were not reluctant to follow natures' paths. That is why they were really precise on the exact  events of when they blessed their seeds, planted, harvested and when to nurture the land for the next crops.
