2) The glory of Gāyatrī. If one recites Gāyatrī once one will be freed from all sins done at that time; if one recites it ten times all the sins done on one day will be washed away. Thus, if one recites it a hundred times the sins of one month; thousand times, the sins of a year; one lakh times, the sins of his life time; ten lakh times, the sins of his previous birth; hundred lakh times, the sins of all his births, will be washed away, If a man recites it ten crore times he becomes a realised soul and attains mokṣa. (Navama Skandha, Devī Bhāgavata).
