The problem is discussed in Relativistic Lagrangean framework with the variable proper mass. It is shown that the so-called self-energy divergence for the 1/r graviational potntial can be eliminated within the variable proper mass concept. The problem has many aspects outlined, which should be further investigated before the final conclusion could be made.General Physicstext
