In the book, The Bhagavad Gita: The Song of the Exalted Self, 1999, by Owen Slight, the author states that Harold W. Percival's Thinking and Destiny, like the Bhagavad Gita, reveals relevant, instructive and long lasting lessons regarding the higher self and the human plight—long lost lessons of everlasting truth contained both in the Sanskrit Bhagavad Gita and Thinking and Destiny. Both books contain complete systems of knowledge. The plight of Arjuna is shown by Percival to be our own.Slight, Owen, The Bhagavad Gita: The Song of the Exalted Self, Owen Slight Publisher, 1999 , 9780646356020
