  • A normal liver should NOT have this much bile pigment, in fact bile pigment in a normal liver biopsy should be scarce!
  • Bile accumulations. Why does it look like a lot is BETWEEN hepatocytes in early stages?

  • 88. Silence… To the question "Who am I?" the only relevant answer is silence. You need to discard all answers in words, including "I am Nothing" or "I am the Cosmic Self" or "I am the Self" - and just stick to the question "Who am I?". All other answers are just thoughts. Thoughts can never be complete. Only Silence is complete. Thoughts are not the goal in themselves. Their goal is Silence. When you ask the question "Who am I?" you get no answer, there is silence. That is the real answer. For your soul is solidified silence. This solidified silence is wisdom, is knowledge. The easy way to silence the thoughts is to arouse the feelings. For, through feelings only peace, joy and love dawn. And they are all your very nature. - Sri Sri Ravishankar
