Pure love would never change - An illustration

Many students are with pure love as long as they are in our institute but when they go out, they say their mind changes due to bad company or due to some situations. This is not correct. If truly you have pure love in your heart, it should not change wherever you are. No society or nobody can change you. One example for this. Suppose we draw the picture of a creeper with flowers on a paper. When this is exposed to the wind, however strong the wind may be, only the paper moves but not the creeper drawn on that. Same way, though your mind may shake temporarily due to some bad company, your heart will be steady. It is not possible for anyone to change the love in your heart. So, it is your heart that is to be filled with love but not merely mind. Mind is only a form of your combined thoughts. This will change with the change of your thoughts. So fill your heart with sacred feelings and true Love and keep it safe.
