The process of learning is the complementary process of teaching. You can gain more skill, knowledge, and experience from teaching.
If you are a teacher in a spiritual community, it is quite common to find people in the group who do not respect you, and who seek to undermine your authority, or belittle you in subtle ways. In such instances, it is wise to remember that in any spiritual group, there will always be sheep, as well as wolves in sheep's clothing. It is not your job to sort them out. Rather than become discouraged, or get into a bickering contest, focus instead on always giving of your very best, regardless of praise or appreciation. Your chief point of comparison should be yourself, and how well you are holding to your own values. Let the world's opinion come and go.
