‘It is possible to learn from a teacher whose identity is completely unknown to the student. This may sound unbelievable, so prepare yourself for something strange. The teacher may be a consciousness that may or may not even reside in a living body. The teacher may have died and yet not have been reborn. Or, the teacher may at present be a child who, in a past life, attained some sort of mastery. It may be that the teacher had a strong connection with the student but passed on. Or, the teacher may have had no connection in this life but, rather, in past lives. Or, the connection may even be much less fathomable. The student may not even be consciously aware of being taught through ‘spirit’. Such an awareness, however, can make the process more efficient. If the instruction is coming, for example, through dreams (as mine most often does), the student can do various things to increase the likelihood that contact will be made and that what is received is consciously retained upon awakening. Future contacts can be initiated by consciously desiring the contact to be made. Retention can be increased by an awareness that an important process is taking place. The knowledge that you are being helped in spirit adds an extra keenness to your receptivity.’
