Lotus or not?

Dear Venerable,
Is a posture like that of the lotus required for the practice of meditation? Should we favor the posture or a requirement in the concentration? Thanks in advance.

Venerable Nyanadharo: In his teaching, the Buddha prescribed to practice vigilance according to the four postures: sitting, standing, walking and lying down. It does not matter therefore the configuration of the posture if the meditator is present in his body and in his mind from moment to moment, without concealing what does not suit him and without fixing on what suits him. And then, after all, isn't the future Buddha Maitreya represented seated on a very comfortable chair!
