Rôhatsu sesshin: intensive meditation retreat

During the first week of december the traditional Rohatsu sesshin will take place. This is a unique opportunity to deepen one's practice by plunging, in silence, into sitting meditationzazen.

Rôhatsu's literal meaning is "the eighth day of the twelth month". The 8th of december is traditionally kept as a commemoration of the awakening of Shâkyamuni Buddha. It was on this day that Shâkyamuni was enlightened when he saw the evening star after having spent several weeks in zazen.

In order to celebrate this historic occasion zen temples organise a Rôhatsu sesshin.

The specificity of this sesshin - retreat - is that it involves a more or less continuous practice of zazen for 12 to 14 hours a day, in complete silence and with only minimal teaching or samou. Everything is focussed on zazen which starts very early in the morning and finishes around 9:30pm.

The teaching will be given by the Buddhist Master Olivier Reigen Wang-Genh. 

All health security rules are in place at Ryumonji. They will be communicated to you upon arrival.
