paragraph_text: Throughout her career Madonna has been involved in writing and producing most of her own music. Madonna's early songwriting skill was developed during her time with the Breakfast Club in 1979. According to author Carol Gnojewski, her first attempts at songwriting are perceived as an important self-revelation, as Madonna said: "I don't know where [the songs] came from. It was like magic. I'd write a song every day. I said 'Wow, I was meant to do this'." Mark Kamins, her first producer, believed that Madonna is "a much underrated musician and lyricist." Rolling Stone has named her "an exemplary songwriter with a gift for hooks and indelible lyrics." According to Freya Jarman-Ivens, Madonna's talent for developing "incredible" hooks for her songs allows the lyrics to capture the attention of the audience, even without the influence of the music. As an example, Jarman-Ivens cites the 1985 single "Into the Groove" and its line "Live out your fantasy here with me, just let the music set you free; Touch my body, and move in time, now I know you're mine." Madonna's songwriting are often autobiographical over the years, dealing with various themes from love and relationships to self-respect and female empowerment. Her songs also speak about taboo and unconventional issues of their period, such as sexuality and AIDS on Erotica (1992). Many of her lyrics contain innuendos and double entendre, which lead to multiple interpretations among music critics and scholars. Madonna has been nominated for being inducted into the Songwriters Hall of Fame twice, for 2014 and 2016 ceremony. Rolling Stone listed Madonna at number 56 on the "100 Greatest Songwriters of All Time".

paragraph_text: With the example of the Ming court's relationship with the fifth Karmapa and other Tibetan leaders, Norbu states that Chinese Communist historians have failed to realize the significance of the religious aspect of the Ming-Tibetan relationship. He writes that the meetings of lamas with the Emperor of China were exchanges of tribute between "the patron and the priest" and were not merely instances of a political subordinate paying tribute to a superior. He also notes that the items of tribute were Buddhist artifacts which symbolized "the religious nature of the relationship." Josef Kolmaš writes that the Ming dynasty did not exercise any direct political control over Tibet, content with their tribute relations that were "almost entirely of a religious character." Patricia Ann Berger writes that the Yongle Emperor's courting and granting of titles to lamas was his attempt to "resurrect the relationship between China and Tibet established earlier by the Yuan dynastic founder Khubilai Khan and his guru Phagpa." She also writes that the later Qing emperors and their Mongol associates viewed the Yongle Emperor's relationship with Tibet as "part of a chain of reincarnation that saw this Han Chinese emperor as yet another emanation of Manjusri."

paragraph_text: ``Next to Me ''was referred to as the band's first love song. Dan Reynolds, lead singer of the song, admitted that it was an unexpected theme change in the interview with Lowe, saying:`` Yeah I do n't typically write love songs. I started writing when I was about 13 years old and it was a source of an escape from school from depression from feeling lost and it was never a romance. So for me this is some of the first times that I've really explored diving into my mind and musicality and sonicality of romance.'' He regarded it as ``something everybody can relate to '', which is the`` feeling like you are going to fail sometimes in a relationship and the true value of a relationship is what happens then''.

paragraph_text: After its release, Evita garnered critical appreciation. Zach Conner from Time magazine commented, "It's a relief to say that Evita is pretty damn fine, well cast and handsomely visualized. Madonna once again confounds our expectations. She plays Evita with a poignant weariness and has more than just a bit of star quality. Love or hate Madonna-Eva, she is a magnet for all eyes." Madonna won a Golden Globe Award for Best Actress in Motion Picture Musical or Comedy for the role. She released three singles from the Evita soundtrack album, including "You Must Love Me" (which won an Academy Award for Best Original Song in 1997) and "Don't Cry for Me Argentina". Madonna was later presented with the Artist Achievement Award by Tony Bennett at the 1996 Billboard Music Awards. On October 14, 1996, Madonna gave birth to Lourdes Maria Ciccone Leon, her daughter with Leon.

She had reached another turning point in her career, reinventing herself and her image with the public." Her relationship with Carlos Leon ended in May 1997; she declared that they were "better off as best friends." After Lourdes' birth, Madonna became involved in Eastern mysticism and Kabbalah. She was introduced to Jewish mysticism by actress Sandra Bernhard in 1997.
