Sati,Sabai,Cleansing,Stillness

The 15 minutes meditation helped to discover myself.
I felt my sati needed more of letting go and being at rest within myself.
I was able to be calm for around 8 minutes and then I was able to hear background noises.There was heaviness in my chest,eyes did flutter open now and then.
I then started counting my breaths inhaling and exhaling in and out.
Very less thoughts came and the heaviness in chest rapidly came down.
I felt I needed more practice to take off like a flight in meditation.
I felt calm after doing this exercise.
Thank you
