In a popular telling of the Ramayana, the old devotee Shabari waits for Rama and gathers berries for him. “She would pluck one, taste it and, if it was sweet, she would put it in her basket, discarding the bitter ones.” Rama accepts the berries she has tasted.
The writer Devdutt Pattanaik notes that there is “no reference to this either in the 2,000-year-old Sanskrit Valmiki Ramayana.”
