  Recently an orthogonal state based protocol of direct quantum communication
without actual transmission of particles is proposed by Salih \emph{et
al.}{[}Phys. Rev. Lett. \textbf{110} (2013) 170502{]} using chained quantum
Zeno effect. As the no-transmission of particle claim is criticized by Vaidman
{[}arXiv:1304.6689 (2013){]}, the condition (claim) of Salih \emph{et al.} is
weaken here to the extent that transmission of particles is allowed, but
transmission of the message qubits (the qubits on which the secret information
is encoded) is not allowed. Remaining within this weaker condition it is shown
that there exists a large class of quantum states, that can be used to
implement an orthogonal state based protocol of secure direct quantum
communication using entanglement swapping, where actual transmission of the
message qubits is not required. The security of the protocol originates from
monogamy of entanglement. As the protocol can be implemented without using
conjugate coding its security is independent of non-commutativity.
