The unity and solidarity of the inner planes make it possible for the Master to use his disciple as an instrument for his work even when the disciple is unaware of serving this larger purpose of the Master. This is possible because the disciple, through his love and understanding of the Master as well as his obedience and surrender, establishes a rapport with the Master and comes to be in tune with him. Those who come into direct contact with the Master receive his direct help, and those who are closely connected with his disciples receive the Master’s indirect help.
