It was documented in the mid 19th century over the course of Gunatitanand Swami's 40 year tenure as the Mahant of Junagadh Mandir.
[1] Through his talks, Swamini Vato, Gunatitanand Swami gave advice for every aspect of life and beyond.
Topics ranged from the glory of God, and how to gain spiritual knowledge, to how to attain peace and happiness.
The notes were later studied by Achintyanand Brahmachari, after being asked by Gunatitanand Swami to continue giving discourses on these topics.
The BAPS sect has published a new edition of the Vatos which includes the addition of two more prakrans compiled by Krishnaji Ada, another disciple of Gunatitanand Swami, based on claims of the latest research and critical study of the original text.
