Macbeth’s words after the discovery of Duncan’s death, Scene iii, lines 107-109 (p. 38,

Had I but died an hour before this chance,

I had lived a blessèd time, for from this instant

There’s nothing serious in mortality.

All is but toys. Renown and grace is dead.

The wine of life is drawn, and the mere lees

Is left this vault to brag of.

Explanation:

William Shakespeare's Macbeth tells the story of how the main character Macbeth brought about his own downfall. With the constant pressuring from his wife Lady Macbeth and his own desire to be the most powerful, aided with the prophecy of the three witches, he did deeds that are even murderous to bring power to himself.

In Act II scene iii, we find the discovery of King Duncan's murder. Acting surprised and shock, Macbeth declares his grief at the death of his lord. He claimed "Had I but died an hour before this chance,/  I had lived a blessèd time". He went further to state that "Renown and grace is dead. / The wine of life is drawn, and the mere lees / Is left this vault to brag of." His statement of " from this instant / There’s nothing serious in mortality. / All is but toys" is a complete lie for from the death starts his own ascend to power, paving the way for his own growth to power.
