An application of the Onsager's principle of the least dissipation of energy to the
problem of the heat conduction in an anisotropic crystal is revisited. In the case of a
steady spatial distribution of the temperature it is shown that this principle is
equivalent to the principle of maximum entropy production. This means that components of
the actual heat flux are distributed in such a way as to achieve the state of the maximum
entropy production.
