In 1962 the Shankaracharya was asked if the practice in his Advaita tradition was compatible with Ouspensky's teaching of the Fourth Way. He replied:

"Yes, there couldn't possibly be any difference. He says that in his System, they take from all the three sources. In the system or 'Way of Action' they purify the heart so as to perform any action and yet be detached from it. The 'Emotional Way' is the 'Way of Devotion and Service'. With that an atmosphere within is created so as to serve the Absolute and receive His Grace. The third, Intellectual Way, is to make Reason work and clarify all the questions met with on the Way, and then if everything is brought together, we hope we are on the 'Way of Understanding', the Fourth Way."

Within Rodney Collin's most relevant contributions, it is the emphasis on the idea of Fourth Way schools existing in different times. He says:

"Schools of the fourth way have existed and exist, just as schools of the three traditional ways existed and exist. But they are much more difficult to detect, because - unlike the others - they cannot be recognized by any one practice, one method, one task, or one name. They are always inventing new methods, new practices, suitable to the time and conditions in which they exist, and when they have achieved one task which was set them they pass on to another, often changing their name and whole appearance in the process."
