Once you attend to something, you are forever intertwined with that thing, and depending on how you framed your attention on that thing, those parameters guiding your perception of that thing will determine the type of influence that thing has over you and vice versa.
When you grab someone’s attention, you are confusing them for an imperceptible moment, in that moment is prime substrate for injecting seed energy, or an idea, or a hook.
Here is a fun experiment. Go into a meditation with the intent to program a seed construct designed to do whatever it is you can imagine and feel confident constructing with efficiency, that you will then implant into someone’s subconscious.
The way you will do this is to install a mechanism that will attach this seed to whatever attention getting method you have for someone, a mechanism that will have symbolic relevance to the seed program you are going to implant in the targets subconscious.
For instance, a mnemonic phrase you will yell or say to someone, a phrase that you will imbue with the seed program energy. Have this seed ready in your laser focused concentration, and the moment before and as their attention switches unto you, is when you release the seed into the back of their mind.
