DIO's Diary (DIOの日記, DIO no Nikki), also known as The Way to Heaven (天国へ行く方法, Tengoku e Iku Hōhō), is a key item referenced in the sixth part of JoJo's Bizarre Adventure, Stone Ocean.
Jotaro Kujo finds the diary after the events of the third part, Stardust Crusaders; considering it dangerous, he burns it. However, because he remembers its contents, he becomes the target of Enrico Pucci, who aims to extract his Memory Disc.
The diary contains the vague details of a plan to attain "Heaven". It is unknown how DIO discovered these specific steps.
Jotaro reading the Diary, as seen in his Memory Disc.
What lies beyond my Stand is the way forward for humanity. What I need is a trustworthy friend.
He must be someone who can control his desires. Someone without a lust for power, honor, wealth, or sexual gratification. He must be someone who puts the laws of God before the laws of humans. Will I, DIO, meet someone like this one day?
What I need are the souls of at least 36 sinners. The souls of sinners contain incredible power.
I'll engrave these words onto my Stand so that I won't forget myself. What I need is courage. I must have the courage to part with my Stand.
As it disintegrates, my Stand will absorb the souls of the 36 sinners. As a result, something new will be born.
Whatever is born will awaken. It will recognize the 14 phrases that my trusted friend will utter... I will trust my friend and become his friend.
Finally, what I need is an appropriate location. Go to 28 degrees 24 minutes north latitude, 80 degrees 36 minutes west longitude...
Hitsuyō na mono wa "watashi no Sutando" dearu. "Za Wārudo".

DIO's Bone is used as a substitution for DIO's Stand, The World. The 36 prisoners and DIO's bone combine, forming a large system of grotesque tree and root-like structures. A knot of roots in this system houses the Green Baby.
After its birth, the "14 phrases" Pucci speaks indeed induce an effect on the Green Baby.
