我引述几句Q’uo的传讯，我认为能稍微阐明你的这几个问题：
首先是1、4、5：
This is a part of the original Thought of the creation, that each of the parts might fulfill their desires.
For through service, one builds one’s awareness of truth. This is the reason for life, as you know it, in the physical. The reason is to experience service. For this is very effective in creating a deep and complete understanding of the Creator’s plan for the creation. In this plan was the concept of service. Through His love, He instilled in each of the parts of this creation the desire to serve. This desire to serve is within everything that exists. It is within the planet that you walk upon. It is within the vegetation, the atmosphere itself. Everything about you exists to serve.
Instrumentality is a mystery, my friends.
Service is the dynamic expression of unity.
总结一下就是造物者的原初想法就是每个实体都能满足其各自的愿望，既包括自己的愿望又包括他人的愿望，我觉得满足愿望的行动（action）就是服务
然后3：
The beingness is the first act of selfishness or unselfishness, of radiance or absorption.
there are, shall we say, imbedded or programmed the opportunities that will open a new avenue of seeking, perhaps of serving, always of learning.
我觉得如果一个行为是一个服务行为，那么不是sto就是sts或者两者的混合（如果desire不纯粹的话）但是行为应该还包括其他行为，如seeking, learning.
