Hi, it’s great to know Headspace has been so useful in your life and thanks for all the kind words.
In answer to your question, yes, it is not uncommon when learning to meditate to become more aware of physical sensations. This can sometimes be aches and pains we were not previously aware of, or the feeling of our heartbeat, our pulse and so on.
Every person reacts to this differently. Some people have an underlying sense of frustration in their life and so they tend to react toward the feeling or sound with irritation. Some people have an underlying sense of hopelessness in their life and so they tend to react toward the feeling with self-pity. Others have an underlying sense of happiness and optimism and may well react with a sense of joy in feeling they are alive. So experiencing anxiety in relation to the sound or feeling simply suggests that there was already an undercurrent or predisposition toward anxiety.
This may not sound like good news at first, but it is part of the process of becoming more aware, of letting go. So please don’t be discouraged. Right now there is a loop in play, where the mind feels anxious and is, therefore, anxious as to how the meditation will play out. As a result, the body begins to experience sensations related to anxiety, such as an increased and strengthened heartbeat. In turn, the mind recognizes this feeling as something to worry about and ramps up the intensity of anxiety. And so it goes on.
So we need to find a way to step out of the loop. Next time, when you feel the pulse, rather than trying to calm it down or get away from it, and rather than trying to focus on the breath, simply give the feeling your full attention. What exactly are you focusing on? Is it the sound or the sensation? If it’s the sensation, where do you feel it? How would you describe the sensation? How would you describe the intensity? Simply be curious, without getting caught up in the anxiety itself. You are learning more about it and thereby changing your relationship toward it.
I would suggest staying with Take10 for now, just until you feel more confident again. But in short, it’s all good and there is nothing to worry about at all.
