Warning: Watching the following segment will probably give you a serious case of the sads.

Gospel great Cissy Houston stopped by the Today show this morning to talk about her new book, Remembering Whitney: My Story of Love, Loss, and the Night the Music Stopped — and while the singer remained calm and composed even as Savannah Guthrie asked tough questions about her daughter’s drug abuse, Cissy’s quiet, stoic grief was somehow even more poignant than hysterics would have been.

The 79-year-old is still clearly in mourning — “I miss her so much I can’t even express it,” she said at one point. Cissy told Guthrie that she doesn’t blame Whitney’s ex-husband Bobby Brown for anything, and that sometimes tragedies are just inexplicable — “Good mothers and good fathers and good families don’t always have great children. Bad people have good children… It’s all their responsibility when they get to a certain age to choose their way. [Whitney] was taught, she knew the way.”

In the end, Cissy said, she’s trying to accept Whitney’s death as part of a higher power’s plan: “I trust in God, and his ways are not our ways. So we have to go with that, and there’s nothing I can do about that.” Can somebody pass the tissues?
