Let's consider a Grail of water analogy. "I AM" the organizer of this thought experiment. I poured water to the Grail upto the half of it and kept the rest of the jug of water under the shelf. Then I will invite people to my house to enjoy the nice cold Grail of water in a hot summer day. Before I offer this grail of water to my guests, the only expectation I have that the guest will be polite and understanding of my sincere efforts. Before I offer them the half full Grail of water, I will ask the following question to the guests:

"How much of the Grail is filled with water?"

There are mainly two versions of the answers: 1) The glass is half full. 2) The glass is half empty. Now, let's analyze the answer. Which of the answer is correct one? Actually, both of them are equally correct but one will take you towards emptiness and others will take you towards fullness. One will take you towards completeness, the other will take you towards incompleteness. What is your intrinsic goal? Does your heart crave for completeness? If yes then you ought to say that the Grail is half full. In contrast, those people who say the Grail is half empty are actually complaining for not being full. Because if not completely full, for them, it is not full at all. He is accusing it for not being full. Although, superficially it seems to be a silly situation of no intrinsic value, this distinction of half fullness or half emptiness, has a profound significance in the deeper level. Once you have the inclination to complain about incompleteness, you are just entangling yourself and making your goal of filling the Grail to the brim difficult, if not impossible. Your goal is to fill the Grail with water in the first place, remember? 

Once you allow yourself in accuser position in an ambivalent or equally true situations, you immediately become blindfolded. I agree, both are true, but you are preventing yourself from seeing the hidden truths and you are actually actively moving away from the truth on your own volition. Once you are in accuser mode, you will only see the half empty Grail, nothing else. Because you are complaining about the half empty Grail, out of this disappointment you will reject to take that half empty Grail of water (because you went there for a full Grail of water), start putting some words or thoughts as an expression of your anger and you will eventually abandon the half Grail and leave the house altogether and start a new search for full Grail. Isn't it counterproductive to your original intention to have the full Grail? Unfortunately, once you have chosen, on your own volition, to be on accuser mode, you cannot see the reality "as it is" because the very act of accusing will block your vision to see the situation clearly. In contrast, if you see the Grail as half full, only then you will see the fact that, somebody has already filled half of the Grail for you in first place. If you can see this simple fact, your inner wisdom will tell you to look for the person who filled the glass. Unless you have this question in your mind, you cannot even think of looking for the Waterbearer. Unless you see the Grail as half full, your inner self will not guide you to ask the critical liberating question of "Where is the Grail filler?" The question will then lead you to the person who has the water, waiting for you to be asked to fill the Grail with water to the brim. And thus your original desire to have a full glass of water fullfilled. 

Do you know what is the source of your accusative mindset? You think, it's entirely your own volitional, right? Do you know why the other guys did not complain about the half-fullness of the Grail? What is the difference here? But you, on your own free choice, took the side of accusation. Eventually this choice prevented you to ask the right question and hence to see the hidden truth. Now what is the operating force here that you are in agreement? Accusation. Is it your own choice? Yes. Then you should not complain for not finding the truth, because you chose not to. Keeping these answers in mind, allow me to share some surprising information with you. The word Satan literally means "The Accuser". The word Iblis means "He/it that causes despair". Did you chose the path of Satan/Iblis on your own choice? Did the scriptures tell you that Satan is smarter than you can think ? Did not your scripture tell you that Satan will give you an impression that you are not doing anything wrong and you are just exerting your innocent free will? 

The moral of the story is: Don't be in accusative mode in ambivalent or ambiguous situations. Have doubts in everything unless your own wisdom agrees. In the same time during your doubt periods, give everything the benefit of doubt, not the malice born out of your doubts. Believe in goodness behind people's action, instead of accusing them for their deed. Hate the sin but not the sinners. Most of sinners did the sin because they had to, with some exceptions such as psychopaths. Still, in most of the cases the sinner is victim of the situations. If you have the true mindset of hating the sin but not the sinners, only then you can perceive the truth that created the situation for the sinner. This is the one of the Grand rules for your salvation! These small truths, little by little, will take you to the Ultimate Truth. This is exactly why all the great traditions require you to be a free thinking, good hearted man with straight and square in actions, before they will even consider you for initiation into the Grand mystery, because without this mindset you will not understand it, even if they tell you the mystery in simple language. And if you are truly a good hearted, upright man and you ask with utmost sincerity, you will be given the answer from within without any external help ie. the scientists, the guru, prophets or mystery schools.
