What you call the spiritual master or teacher or guru is not the person. The guru is eternal. The guru's inspiration, the guru's force, the guru's divine energy, the guru's vibration will always be there guiding you, directing you. The help that can be given through the physical body is limited; on the spiritual level, the guru can help you much more. Always try to communicate at that higher level. In your practices, in your meditation, you should learn to communicate with the spiritual part of the guru.
The guru need not consciously give you blessings and teaching. If you are ready to receive it, even he cannot stop it. The more you follow the teachings, the more you have the guru's presence and communicate with the guru. The teaching is the guru. The teacher is only a vehicle.
If I am giving a talk, I am the one who is speaking, not the microphone. But you hear the talk through the microphone, through the speakers. The real speaker is the spiritual part that simply functions through this machine. For some time you might need the speaker, but you shouldn't depend on that always. Learn to receive the message without the help of any machines. That way you can have the guru with you always.
Om Shanthi, Shanthi, Shanthi
