Mahaperiyava has recommended chanting mooka pancha shathi to many devotees. If you read this srimukham Mahaperiyava gave to Mooka Pancha Shathi you will know his bhakthi towards this stothram http://valmikiramayanam.in/?p=3138
Sri Govinda Damodara Swamigal chanted mooka pancha shathi every single day of his life from his 10th year and attributed all his spiritual growth to this stothram.
