What is the ruling on working in the field of human development, which many have come to see as based on fraud and the business of words?

The field of human development is divided into two parts: The first is esoteric, dangerous in methodology, and corrupt in its approach, not free from philosophical fallacies, erroneous assumptions, and theories, along with esoteric practices and possibly pagan rituals. The second is beneficial and useful, such as courses related to life planning, goal setting, time management, child rearing, the art of family relationships, and the arts of dialogue, communication, and public speaking. So, if the questioner confines his work to what is free from religious prohibitions, then there is no harm in this work, and no objection to the income derived from it.
