Soli,
That is the nature of the unrestrained mind, to run off in many directions and create distractions, etc., etc. It you can get your mind to be still for a few minutes - as you say - then you are already a Master. It is said that if you can still the mind for one second you would have achieved samadhi, nirvana, the Awakening, etc., etc. Yes, the mind is like a drunken monkey who has been stung by a hive of bees.
I think your real question has to do with entering the silence. Don't allow your mind to trick you with its distractions that you are no entering the silence. Laugh, but that is just what is happening here: crazy trick of the mind.
Entering the silence is part of the visualization process. You are actually using your mind to enter the silence. That is, immagine - which is itself a sub play on the mind stuff - you are entering this deep, profound and beautiful silence. Doing this actually preoccupies the mind and sorts of trick the mind into silence by causing it to be purposely absorbed into this immagining or visualization (which ever label you prefer).
By the way, SFQ is particularly effective in accomplishing this effect: the entering of the silence. Why and how? Easy! There are a series of things which comes into play with the proper execution of SFQ as Master Lin presents the teaching. For example, look at what is involved in the Level 1 Active Exercises: the smile on your face, relaxes the entire body; the calling upon the Master's energy or help directs and focuses you in the right direction; the breathing and its visualization of the incoming healing and the outgoing scattering of diseases and blockages, etc., etc. all work to create a synergistic effect of quieting the mind and instilling this silence. Note, also, the profound effect of the gently and slow movements. Working together, they all combind effectively to quiet the mind through what I call this subtle distraction (sort of using the same mind trick on the mind). Many other schools or paths teach the same strategy, but SFQ uses a combination of the best of all the paths. And, most important, it works!
Relax, smile, enjoy the practice, and in time you too will have the experiential-knowledge of THE SILENCE .... Rome wasn't built in a day. The process, the journey and the destination will come together for you, just relax - SMILE!
Silence....
