Question: Should I be aware of noises in the room, or is the goal to become unaware?

Babaji: I do understand. It would be better if you could choose a peaceful location. There were several noises there. If it is one type of noise then you can concentrate on that noise. Even if due to circumstances, there are some noises try to concentrate in between eyebrows and try to visualise that the sound is coming from within only. Then your mind gradually ignores the outside as it progresses in concentration. Like you have observed, when you mind has been conscious of one thing it hasn't been able to be conscious of another as the concentration progresses.
