How did the narrator in Chapter 19 describe his personal experience of serving his Guru for twelve years?

The narrator recounts his twelve years of service as a time of immense love and profound spiritual absorption. As detailed in Chapter 19, his Guru was a 'veritable idol of devotion and love' who raised him from a child, ensuring there was no shortage of food or clothing and always protecting him.
