This technique has three steps.
First, feel an object or person before you. Do not just see the object or person, but feel the object or person, become completely lost in them.
Second, feel the absence of all other objects and persons but this one. Exclude everything else. Just be completely absorbed with that one object or one person.
Third, when you really feel there is no other object or person, when you have achieved the state of excluding everything or everyone else, then unclutch from that one object or person also.
Next, leaving aside the object feeling (being absorbed in one object) and the absence feeling (that one object is absent also), realize yourself. Disappear into yourself. Suddenly, you will see you are centered on you, on your deeper Self, on your consciousness, on your very being.
If you are in love with an object or a person, try this technique. First feel the presence of that object or person and the absence of all other objects or persons. Then feel the absence of that object or person also, and you will become centered on eternal bliss.
