  In this paper we examine the interaction of $D N$ and $D^* N$ states,
together with their coupled channels, by using an extension of the local hidden
gauge formalism from the light meson sector, which is based on heavy quark spin
symmetry. The scheme is based on the use of the impulse approximation at the
quark level, with the heavy quarks acting as spectators, which occurs for the
dominant terms where there is the exchange of a light meson. The pion exchange
and the Weinberg-Tomozawa interactions are generalized and with this dynamics
we look for states generated from the interaction, with a unitary coupled
channels approach that mixes the pseudoscalar-baryon and vector-baryon states.
We find two states with nearly zero width which are associated to the
$\Lambda_c(2595)$ and $\Lambda_c(2625)$. The lower state, with $J^P = 1/2^-$,
couples to $D N$ and $D^* N$, and the second one, with $J^P = 3/2^-$, to $D^*
N$. In addition to these two $\Lambda_c$ states, we find four more states with
$I=0$, one of them nearly degenerate in two states of $J=1/2,\ 3/2$.
Furthermore we find three states in $I=1$, two of them degenerate in $J=1/2,
3/2$.
