What is the role of a spiritual guide?

Spirit guides are not always attracted to those whom they direct, though this is usually the case.

Sometimes, they are selected for their own fitness. 

They are naturally apt to teach.

Sometimes, they are charged with a special commission.

Sometimes, they are picked because they are able to supply what is wanting in the characters, which they train.

Sometimes, they select a character, which they wish to mould. 

This is a great pleasure to the higher spirits.

Sometimes, they desire, for their own spiritual progress to be attached to a soul whose training is irksome and difficult. 

They toil upward along with the soul.

Sometimes, they are attracted by pure affinity―or by the remains of earth love. 

Very frequently, when there is no special mission for the soul, the guides are changed as the soul progresses.
