For instance, knowing that $L_c(\psi)=0$ already tells you what $\psi''$ is in terms of $\psi$ and $\psi'$. Similarly, taking higher derivatives of the differential equation, $\frac{d^n}{dx^n} L_c(\psi)=0$, lets you obtain the higher order derivatives in terms of the lower order ones. This is very similar to solving the ODE by power series. However, you need to know $\psi$ and $\psi'$ to get anywhere with this method. If this is not what you need, please make your question more precise.
