For the record, here are the three references, yes, the only three references to "unconditional love" in the WT Library CD:
*** g03 6/8 p. 4 Are Values on the Decline? ***
AMONG the greatest gifts parents can give to their children are unconditional love and a set of values that the parents live by and do not just lecture about.
Without proper values, life is little more than a crude struggle for survival. Values give meaning to life. They establish priorities. They set moral boundaries and define rules of behavior.
*** g92 5/22 pp. 11-12 Help for Adult Children of Alcoholics ***
"My father’s behavior was so shameful that his shame rubbed off on me. To compensate I tried to be perfect. I gave and gave, trying to buy love, never feeling worthy of unconditional love. My life became a performance, with feelings frozen. Years later my husband and children told me I was a robot, mechanical. For 30 years I had slaved for them, sacrificed my emotional needs for theirs, given to them as I had always given to my parents. And this was my thanks? It was the ultimate wound!
*** g82 3/22 p. 24 Psychiatry Goes to the Dogs ***
Dr. Calabro explains: "Dogs give love—unconditional love. They ask for attention, and when someone responds, they give love and security and warmth in return, with no strings attached." Some psychiatrists resist pet therapy, Calabro says. "They say, ‘Here we are, spending 10 or 15 years in school learning all about psychiatry and drugs, and all these people do is bring a dog in and look what happens. There’s got to be more to it than that!’"
