A common person has many leakages. This leakeges spend our pure mind energy. due to this expenses our mind dont gain profit, we do not become intelligent. The very first leakage of our mind is of I centre i. e intelligent centre. when we are thinking on any subject we find that we drift from that main subject. if suppose we are talking about PM modi and in between started talking about mayawati i. e drift. all the time when mind is drifting from main subject it is spending energy, this spending of energy is basically spending intelligence centre energy. example if you met one of your friend and you started gossiping there you are spending your energy and instead of that if you have used that on reading or finding solution to your problem then that would be more benificial. Now we will see the leakages of E centre i. e emotion centre if you are thinking of your ex girlfriend how you two were in love then how your relationship ends. how you hurt her and what not. if thinking your dad had biten you during  childhood or any emotional things from past. our pain, sadness, fear these are nothing but leakages of E centre. now we will talk about leakages of S centre if you are ejaculating at night not for procreation but just for fun thinking of sex is leakage of s centre. we have habit of shaking our head, leg and hand or drumming fingers these are the leakages of M centre. if you are doing something unconsciously then you are spending your energy. due to this kind of leakages our body get strained. this kind of leakages is simply like a open tap allowed to flow the water. there are many leakages that are noticable and non noticeable.The main reason we are doing this is because we want to acknowledge about the present state i. e anger, greed, lust etc. if we dont use our energy judiciously then we will feel lazy and feel low all the time. I have been practicing this from past 1 year but everytime i start it to control wastage of energy in enthusiasm but i failed everytime. all i want to say in simple words is never waste your energy in anger, greed, sex, gossip. these are the main reason behind your weakness and suffering. use your energy properly because this will effect to your intelligence.
