There are no hard and fast rules as to when you should meditate, but to get a real benefit from meditating, it is advisable to dedicate at least one twenty-minute slot every day when you know you will not be disturbed – make time for yourself by unplugging/switching off all phones and devices, and asking any family or friends who are around not to disturb you. Once you make the commitment to meditate, you will find a time to suit your daily routine. You may also like to use a timer that can rouse you at the end of your twenty minutes.
Try to build up to two twenty-minute sessions a day for optimum benefit.
If you are travelling you may have to adapt your time slots but when you are more experienced you can make use of the time on the train or plane to ‘disconnect’ from daily life.
