Please practise in accordance with this Mahasatipatthana Sutta so that you can see why it is acknowledged as the most important Sutta that the Buddha taught.
Try to practise
all the different sections from time to time as they are all useful,
but in the beginning start with something simple such as being mindful
while walking (see Iriyapatha Pabba), or the mindfulness of in and out
breathing (see Anapana Pabba). Then as you practise these you will be
able to practise the other sections contained within this Sutta and
you will find that all the four satipatthanas can be practised concurrently.
A sutta should be
read again and again as you will tend to forget its message. The message
here in this Sutta is that you should be mindful of whatever is occurring
in the body and mind, whether it be good or bad, and thus you will become
aware that all conditioned phenomena are impermanent, unsatisfactory
The original Pali
text of this Sutta can be found in Mahavagga of the Digha Nikaya.
