The national self-interest dictated to Jawaharlal Nehru a policy of non-alignment, which in essence meant keeping an independence of policy, not aligning with power blocs or making pre-commitments, keeping our options open, not taking decisions on pre-conceived notions, and judging each issue on its merits.
The peritoneum is a continuous transparent membrane which lines the abdominal cavity and covers the abdominal organs (or viscera). It acts to support the viscera, and provides a pathway for blood vessels and lymph.
The serous membrane (covering membrane) which, in humans and other vertebrates, forms the wall of the pericardial cavity and holds the heart in place. The pericardium is made of two thin layers of tissue. Immediately surrounding the heart, and attached to it, is the visceral pericardium, or epicardium. The heart can slide easily on the visceral pericardium, thus allowing it to beat freely.
