Chitta is a storage place of our Sanskars (old impressions). Every Sanskar whether it is good or bad is stored there. Sanskars come to Chitta from our five Karmaindriyo, five Gyanendrio, mind, intellect, prana and ego, and are stored there. Chitta is like an open camera. It stores everything and there is no doubt about it. Whatever we think, it's Sanskar is fixated in Chitta. If you keep only happy thoughts, these happy thoughts will be stored in Chitta. Human beings think about sad thoughts even while having happy thoughts. These are two opposite sides of thoughts.
