Is each entry into a new sphere or state marked by a change analogous to death?

Is each entry into a new sphere or state marked by a change analogous to death?

There is a gradual sublimation or refinement of the spirit-body, until by degrees all gross elements are purged away. The higher the sphere the more refined and ethereal the body. The change is not so material as death, for there is no corporeal envelope to lay aside but it is analogous to it in that it is a process of development, the entry of the spirit into a higher state of existence.
