Reasons for too many thoughts could be several. One is lack of enough circulation in the system. Do some vigorous exercise, run, go to gym, do any exercise. Then there is that little exhaustion, not too much. Less than half of your energy is spent on exercise then mind becomes calm.
Second, when your pitta is very high then also there are too many thoughts. So to lower the pitta, take triphala. Or many others drink the amla (gooseberry) drink and all this. Talk to an Ayurvedic physician and consult them to reduce pitta, that is the second thing.
Third, lack of prana, so pranayama will help.
Fourth thing is if your bowel movements are not okay then also too many thoughts will come in the head. So for bowel movements to be good take some triphala, some purgatives. It’s good to cleanse your system, your intestines. Then also your mind becomes much clearer, okay?
So these many ways are there. And even then if it happens, then put on a meditation CD and sit. If you feel it is easier to meditate with a CD on, then do that, it calms the mind. And then from time-to-time participate in advance courses. Silence course will definitely help.
