By teaching and training the vital to wait. One can start with simple things like food and go on to other things wherein one learns to waste.
Become conscious of all haste and hurry in nature and deliberately slow down in all activities.
Practice stepping back and adopting a witness attitude towards life.
Practice inner quietude and peace. Call peace. When impatience tries to take over, do some deep breathing or inwardly repeat your mantra, the mantra that naturally connects us to the Divine.
Affectionately,
