When you feel, presume and assume that
everything else has failed and you don't have the capacity to help yourself
through your own means - then you are NOT at the end. You can always have
the option of pressing the "ctrl+alt+del" and reboot the system and in the
meantime soliciting for divine intervention.
As you may be aware, in the epic Mahabharata, when Droupadi was publicly
humiliated in the King's court, she was keeping her both hands on her chest to
cover her modesty and begged for divine intervention. At that time, Sri
Krishna was sitting with Rukmini and she heard the prayers of Droupadi and
asked Sri Krishna about why he was still waiting to extend the help. He said
that she was of the view that she can still take-care of herself through her
hands, and let's wait when she was completely defeated and ask for me without
any hesitations or self respect. By the time the situation has
crossed its limits and Droupadi irrespective of her modesty and breaking of her
own power on the dress, suddenly raised both hands towards the sky and cried "
Hay! Krishanaa!". Within a fraction of second the relief was arranged and
situation was under the control of the divine power.
It is said that you need to release your attachment to any particular outcome
and remain open to all possibilities. When you visit Tirupati before the
Darshan, you want to inform the God that you have left every thing behind and
wanted to see Him. A symbolic way is that you shave your curly hair, fondly
preserved moustache and the beard. You are leaving the material attachements
and false ego behind before you go for His darshna. That is the meaning of it.
