The E kernel of HH includes five elements: read nonfiction books, visit cultural places, speak three languages, volunteer one week, and join the Hualish community. These are driven by the H and O components in HH, and also follow the rules of P. Each E element often serves more than one element of H, O and P. Some elements are individual in nature (the first three, and possibly the fourth) while others are collective in nature and require simultaneous participation of many members (the last element, and some forms of the fourth). The table below provides a concise summary of these elements, including their most relevant organizational variants.
