In Search of a Word

There's a word for it; One of my favorite words; It often crosses my mind as is the case presently. But it always evades me. Its meaning seems to always find space in my life's spear, and I'd be pleased if I could retain it for good usage. But it always evades me. It often walks onto the doorsteps of my mind and camps out at the doorway of my heart. But it always evades me. It is a physics kind of word that speaks of time and space, of being in a state of indecision or immobilization, only to be mobilized or influenced by an outside force. But it always evades me. If I shall ever recall it again, I must document and shelter it in a special place so that I can utilize it at will. That word fits my life and circumstances like a customized garment. But it always evades me. 053123PS
