There are two questions here and I like the second one. In my mind, there is more danger in managing through spiritual means than secular ones. The spiritual dimension could be seen as effective if one is immersed in a homogeneous setting where all individuals are only one form of religious worship. Even this could be challenging as different individuals within the same faith or string of worship can hold varying perceptions of zeal towards the idea of the sacred. In a heterogeneous setting, secular instruction and management is more effective for a variety of reasons. The first is that it creates a common ground for all individuals that lie outside a specific notion of the sacred. Rather than enforce one form of religious worship and advocate one form over another, the secular nature is one that seeks to work with individuals away from religion, making it an issue for the private as opposed to elevating it in the public domain. Additionally, I would say that management by the secular is more effective because it is probably easier to construct management core visions and principles to a secular vision as opposed to a specifically religious one.
