If we find a difference of opinion in the statement of Sages, it is due to the difference of stages which they attained and, of course, they mentioned what they saw.
Those who rose from the lowest organ by means of Ashtang Yog and terminated in the Tenth Gate saw their own spiritual self there and believed themselves to be the Brahm or Creator of this world.
Sages that started along the stream of wisdom and stopped below the ETERNAL CANDLE in the store of Satogun, the home of Vishnu---one of the terrestrial angels---felt there three objects eternal, i.e. Matter (Maya), Brahm (Spiritual Lord) and Soul.
But Sages who caught the NAME and reached the dominion of the Second Spiritual Lord saw in the ETERNAL TRIANGLE six objects as eternal i.e. Matter, Brahm (2nd Spiritual Lord), Soul, Action, Ishwar (the great judge) and Vedas.
Those who reached the highest stages stated what they saw. There is no difference in their advice as far as the way to salvation of Soul is concerned. As they happened to be amongst people of different culture, customs, habits and languages, there is a difference in language, but the essence of the teaching is the same.
"With eyes, ears and lips closed, if you do not find the secret of God, laugh at me."
