To grow, a plant needs to receive appropriate caresses from the four elements of nature: earth, water, air and sun.
Similarly, we are not only nourished by food. To live we feed from the four elements: we eat solid foods, we drink water, we breath air, and we are charged with solar energy, which is energy that loads the entire system.
So to grow in every way we are also fed by caresses.
And these are what we will incorporate as habits.
