First is to breath infuse the system, any which way.

That helps considerably to bring the mind to order.

If thoughts are noticed, go to the back of the head or link to naad sound if it is available.

Remain there so long as the mind seem to have the tendency to have thoughts.

If you come forward your presence will empower the thought mechanism if that mechanism is in action. The degree of empowerment has to do how indulgent you were when the original event took place which is related to that thought. Like the time when you were with your girl friend. Due to the mental intensity of the event, it has a power which defies your willpower.

The more dramatic was the event, the more power its memory imprint will have to control your attention. This means that you will have to keep a safe distance (by staying at the back of the subtle head) from the related thoughts.

If they are no thoughts, if the mind is found to be silent when you first sit to meditate, you should still go to the back of the head or link to naad sound resonance but look forward. Do not go forward because then you run the risk of having those girl friend related memories arising to control your attention all over again.

Look forward to see if there are any supernatural developments, visions or inspirations. If they are observe them but without pursuing them. If you pursue them, the mind will shift to a lower level and the meditation will sink to a lower plane of consciousness.

It is likely that in some sessions, someone, a yogaGuru or deity, appears or is felt to be present. You should open yourself to such influences.

Also take note of thoughts which defy your authority. Trace these back to the particular memories or persons involved and realize what a whimp you are/were. Then take steps to avoid those type of incidences.
