I believe this to be a song of him thanking the sufferings that he's had to endure throughout his life. He's happy for his past pains and sufferings, because they've given him wisdom.
This has a very nihilistic existential feeling to it. That is, he sees suffering as not only something that must be endured in life, but something that is favorable to have in life.
Of course no one 'loves' suffering. But people can certainly be thankful for the wisdom that they've gained through their sufferings.
