Trapped in a Bank's vault for 3 days !

This reminds me of a lady about 50 years of age who got 

trapped inside a Bank's vault. The lady was busy inside the

vault when suddenly she heard the noise of a big door being

closed. Before she could react she found herself trapped inside

the vault and -of course- darkness prevailed. She was completely

at a loss when she became aware that she would have to stay

there for three days as the bank would remain closed for that

period. She tried every means to get out -shouting at the top of

her voice, knocking at the vault door etc. Finally she recognized

her situation and sat down quietly for some moments. 

She thought and thought for a way out but failed. 

At last she remembered  about Meditation which she usually

practiced but not very seriously. She knew that she would have

to remain there for 3 days without food and water.    To make

matter worse the season too went against her since it was the hot

summer month. As a last resort she decided to concentrate upon

Meditation. After few breaks she went deeper and deeper.

She was still in that meditating mood when the bank opened.
(The matter came out in the Newspapers 10 to 12 years ago )
