A three-week advanced deepening retreat offers the possibility of meditations of more than 24 hours, combined with process-oriented guidance, as well as sessions of walk-and-talk and meditative yoga. After each round-the-clock meditation, an evening seminar discusses meditative processes based on the experiences of the participants. This facilitates the cultivation of subtle levels of free mental attitude and a mentalistic repetition of the meditation sound.

The retreat stimulates gradual, but fundamental processes of inner change aiming at opening the mind for meditative silence. Along with the rest of the programme, round-the-clock meditations seek to loosen the grip that time and body have on us. They help us letting go of our psychological investments and lower selves, facilitating the realization of aspects of the self anchored in a timeless dimension of existence.

Advanced deepening retreats require previous participation in altogether at least six weeks of regular deepening retreats of Acem Meditation, corresponding to 300 hours of meditation beyond the 6-hour level. If you do not yet meet this requirement, you should participate in a one- or two-week deepening retreat instead.

Advanced deepening retreats presuppose a lifestyle without the use of psychoactive drugs, including cannabis
and psychedelics.

After two three-week advanced deepening retreats, it is also possible to practise round-the-clock meditations at 16-day intensive advanced deepening retreats and 9-day intensive advanced deepening retreats.
