How did Radha attain the highest position without sacrifice of work or wealth?

[Radha never did Karma Sanyasa like Hanuman and Karma Phala Tyaga like Sakthuprastha. But she attained the highest position. How do you explain?]

Radha became mad in the love of the Lord and also died subsequently. Madness and death are the two last stages in devotion (Unmado Maranam Tataha). Such a state is possible only for one in millions. Such madness is not given by the Lord but is attained by your own spiritual effort. The Karma Sanyasa and Karma Phala Tyaga are for the people who are living in this world without such madness.
