Belief and Faith

From ancient times people in Indian homes install idols of Lord Ganesha at the main entrance of their home to prevent evil powers from entering their homes and let all that is good flow in. What I have noticed that earlier few had placed these idols at their entrance but now a days I find these at each next door baring a few, also I find people using Vaastu and Fengsui instruments. I feel this to be the impact of the telivision serials which lay stress on these principles now a days. A few years back I never saw people talking of Vaastu , Fengsui or more such things. I don't feel any harm in practising these things because it does not harm anyone. At least you have the peace that everything good will happen and peace is all we need and is difficult to achieve in this fast moving world. Also such acts show that you care for your home and family that why you do such acts to safeguard them. Caring for people, that's a good sign of building relationships and humanity. It's the relations, love and peace of mind that makes a man ive his life happily and faith in god provides strength to face the toughest situations of life.
