A very simple and surprisingly powerful spiritual practice is to remember God as often as possible. Use your creativity to fill yourself and surround yourself with reminders of God: mental repetition of a name of God, holy pictures within your visual field, spiritual music playing on earphones or quietly in the background - use all means available to immerse yourself in non-stop ongoing remembrance of God.
Yes Suryakant, I use this all the time and it is extremely powerful. If it was only possible for me to use one tool this would be the one I would choose. All i use are the mental aspects, and it changes so many things in my life in ways I cannot even describe.
Thank you for sharing your experience, Etherfish. The practice of non-stop ongoing remembrance of God is so simple that it can be added to any other daily practice such as AYP or other yogic activities.
