Re: Nitnem ?
Veera/brother,
There are several things you can do.
Start actively listening to Gurbani and sakhis of the Gurus. Learn to do kirtan and sing the praises of God with love. Go to the Gurudwara and further cultivate feelings of love and humility by cleaning shoes and utensils, do chaur sahib. Participate in the worship that happens there: taking out Guru Granth Sahib, putting it back in the evening, daily readings, kirtan and ardas. It's important to be in a sangat whose goal is the same as yours, to cultivate love and humility.
Whenever you are waiting for something or doing chores around the house/gurudwara, start to remember God, recall shabads you have heard and sung. This will bring about the feelings of love that you were cultivating with previous activities. With this feeling, repeat "Waheguru waheguru..." as you focus your mind on God.
Develop a virtuous character, taking responsibility for your actions and practice truthfulness and honesty. Learn to appreciate others even with their flaws. Do good deeds, open doors, feed the homeless, etc. and be selfless in your service of others. The previous things will help with this. When the mind is focused on God, service become selfless, and it will focus on God only if you feed it with spiritual wisdom by reading, listening and singing.
