the mistake is never the Guru's

A Guru can show the way back home, to your real self. What has this to do with the character, or temperament of the person he appears to be? Does he not clearly tell you that he is not the person? The only way you can judge is by the change in yourself when you are in his company. If you feel more at peace and happy, if you understand yourself with more than usual clarity and depth, it means you have met the right man. Take your time, but once you have made up your mind to trust him, trust him absolutely and follow every instruction fully and faithfully. It does not matter much if you do not accept him as your Guru and are satisfied with his company only. Satsang alone can also take you to your goal, provided it is unmixed and undisturbed. But once you accept somebody as your Guru, listen, remember and obey. Half-heartedness is a serious drawback and the cause of much self-created sorrow. The mistake is never the Guru's; it is always the obtuseness and cussedness of the discipline that is at fault.
