Vibration in relation to people:
In relation to people, how do you know when you get good vibrations or bad vibrations from them? First of all there is a "feeling". Some people do not realize the difference between real vibrational differences and mental judgment. You must keep a very kind feeling within your heart at all times-- a feeling that is absolutely unprejudiced. That feeling can judge better than all the intelligence in the world.
The best way to know what kind of vibrations people radiate is to watch the microphone of your feelings, right in your heart. It is the most sensitive instrument of all. For accurate results, however, you must be free from any attraction to the opposite sex, and from any feelings of attraction or repulsion. A neutral state of consciousness is necessary. When you can use the microphone of pure feeling, which does not judge from prejudice and emotion, then you have developed spiritual sensitivity. The spiritually sensitive man loves everyone~ Paramahansa Yogananda SRF Lesson 117
