Meditated for an hour, it took a long time for the mind to settle, but eventually it did and there was a blissful moment of stillness. Was captivated at one point by a robin singing in the branches of the bush next to my open window.
Life doesn't always play ball with our preferences, so it is good to develop some equanimity towards the world, towards pleasure and pain.
Sometimes it is a relief not to think, to just silently pay attention to the sensations of the present moment as they rise and fall in the body. If you do it for long enough, you can let go of liking/disliking and get very still and unattached and feel like you are just a flame burning in each moment.
The Buddha said that Nibbana is not the end of the mind, it is what fire becomes when it is no longer held by its fuel.
Good news, get completely better soon.
