INNER PEACE by Swami sivananda
Perfect security and full peace is not experienced in this World, because this Worls is in a relative, causal plane. All of World's objects reside and are conditioned by time, space and causation. All objects of the World are perishable.
Real, deep inner peace is independent of worldly external, material conditions. Real, abiding peace is stupendous stillness of the Immortal Soul within. If you can rest in this ocean of peace, all the usual noises of this World can hardly affect you.
If you enter the silence, or the wonderful calm of divine peace, by stilling the bubbling mind and restraining the thoughts and withdrawing the outgoing senses, all disturbing noises will die away.
Cars may roll on the streets; people may shout at the highest pitch of their voices; railway trains may run in front of your house; several mills may be working in your neighbourhood, and yet, all these noises will not disturb you, even a bit.
Where then, can you look for full security and perfect peace? You can find this in the Immortal Self. The higher immortal Self is an embodiment of peace - beyond time, space, and causation.
