The other contents of Soubirous's reported visions were simple and focused on the need for prayer and penance. On 25 February she explained that the vision had told her "to drink of the water of the spring, to wash in it and to eat the herb that grew there," as an act of penance. To everyone's surprise, the next day the grotto was no longer muddy but clear water flowed. On 2 March, at the thirteenth of the alleged apparitions, Soubirous told her family that the lady said that "a chapel should be built and a procession formed".
