Since times immemorial parables have played a role when it comes to ethics, values and wisdom. And, that role has been a word of mouth, often sans level of literacy of the recipient and the giver. While it is important to tell and share what is happening in your head, the role of parables from all regions and religions can never be undermined.
The wisdom curve is definitely sharper when connect is holistic and influence of the narrative has a character to anchor upon. Beauty of a parable is its timing. A story in time has great potential for changing course and resolving conflicts. Sharing stories and seeding wisdom is a far better alternative than sermons and lectures. Storytelling works, if it is from a distance it just works better.
