It might be thought that meditation is about being calm and still, sitting in a still position, calming the body, the breath and the mind. It sounds right, yes, but it's not exactly right. Calming the body is good, to give it peace and rest. Calming the breath sounds good too, to bring about the calm throughout the body. Calming the mind seems more like an essential part of meditation, not getting caught up in negative thoughts or thoughts that go off on tangents.
That all sounds good. But there is more to meditation than that. The benefits of meditation mentioned above are good for the mind and body, but there is a deeper knowing in meditation. You perceive the thoughts that may or may not be stilled. You perceive the breathing that may or may not be calm. You perceive the body that may appear to be still or moving. You see, the mind, the breath and the body can never truly be still. They appear in the World of Motion where everything is in a constant flow of movement. Even if the body appears to be completely still, we know that it is sitting in a spot on a spinning planet that is swirling through the universe.
There is a relative calm that can be brought about through meditation, though not True Stillness. Yet the True Stillness is here. It is the 'place' from which the mind, breath and body are perceived. You are the Stillness that the meditating mind and body is trying to reach. So it doesn't really matter if the mind is flowing, the breathing is heavy or the body is restless. It doesn't matter if the mind feels agitated and unable to concentrate. It doesn't matter if trying to control breathing causes breathing to be unsettled. It doesn't matter if the body is fidgety or uncomfortable. The highest aim of meditation is to just be as you are.
Being as you are requires absolutely no effort. You don't need to do anything. In fact, you don't really do anything. The witnessing of the mind, body and world just happens naturally, without effort. The movement of the world appears in the timelessness of Being. You don't need to try to be calm. You are Perfect Calmness already. You don't to try to be still. You are Timeless Stillness itself.
There's no need to try to achieve peace or indeed to try to stop trying. There's no need to worry about failing. This trying and worrying, succeeding or failing, is a play of the mind perceived by You. You are complete already. You don't need to achieve peace. Whether the mind finds peace or not doesn't affect the peace that you are.
So in meditation when the mind becomes agitated or there is a focus on something, let it go. It doesn't matter. In fact, it's not you holding on, focusing, or letting go. You are the Awareness in which this appears to happen. These instructions are for the mind to let go of its identity with actions and trying to control the world. All is well. You are perfect peace as you are.
The mind may in time come to rest in the timeless peace of Aware Being, but the mind is not you. You are Aware Being already. So is meditation necessary? Not really. Nothing is needed to be the Still Peace that you are. But meditation is for the body-mind to come to the peace of the Aware Being that you are. Meditation naturally happens when the mind withdraws from identifying with the forms of the world.
Of course, you can 'meditate' wherever the body may be, whatever the circumstances. The meditative state of the mind is the withdrawing into the timeless nature of Aware Being that is always present. You are always Here and Now, wherever the mind or body may seem to wander. Even as the Earth spins around the sun, it appears in the Stillness of Awareness. This Peace and Stillness is with the body-mind wherever it goes. The mind will, in its own time, recognise this and find peace.
