PROTECTING THE BIRTH
How do we create and maintain an atmosphere of reverence for what is happening the first moments after a birth? How do we sustain the natural response of wonder and awe that comes with the arrival of the baby? How do we best welcome a new human being? How can we protect them from unnecessary shock, and ensure a good transition into life? The time of birth and the following hour can be protected by the helpers, by keeping things warm, calm and quiet, and keeping the lights low. Even if there are medical things to attend to, it is possible to protect the mood of quiet and gentleness by speaking in a low, warm voice and warding off stress and anxiety. Even someone who was not part of the process and event will feel the mood being held in the room if they are respectful.

The analogy with falling asleep is instrumental in formulating in a simple and concise way the conditions needed for effective labour to establish itself properly: being protected fro useless words, being sheltered from bright lights, being in an atmosphere of privacy, feeling comfortable in terms of temperature and feeling secure.

Radha and Krishna Embrace in a Grove of Flowering Trees,
"Spontaneous labour in a normal woman is an event marked by a number of processes so complicated and so perfectly attuned to each other that any interference will only detract from the optimal character. The only thing required from the bystanders is that they show respect for this awe-inspiring process by complying with the first rule of medicine--nil nocere [do no harm]."
