"dying is an art".explain it with reference to lady lazarus.

The standard interpretation of the poem suggests that it is about multiple suicide attempts. The details can certainly be understood in this framework. When the speaker says she "has done it again," she means she has attempted suicide for the third time, after one accidental attempt and one deliberate attempt in the past. Each attempt occurred in a different decade, and she is now 30 years old. Now that she has been pulled back to life from this most recent attempt, her "sour breath / Will vanish in a day," and her flesh will return to her bones. However, this recovery is presented as a failure, whereas the suicide attempts are presented as accomplishments - "Dying is an art" that she performs "exceptionally well." She seems to believe she will reach a perfection through escaping her body.
