We emphasize the importance of finding the "true" observables of the Einstein theory for canonical quantum gravity. The Hamilton-Jacobi theory for constrained systems is outlined and its application in terms of Ashtekar variables and Dirac variables is discussed. A specific example of a Bianchi II model is solved and the role of one variable as a "time" parameter is indicated. We end with a brief remark about an alternative approach.
