Your dog has no opinions of itself or you.
That’s why it is always pleased to see you, always wagging its tail and is full of joy.
We as humans can also choose this, it simply means that we have to learn to observe and witness our own thoughts without evaluation. This will allow the judgemental thoughts to dissolve as we have not given them energy or acted upon them.
We can then see ourselves and others with no filters, wag our tails and be like the dog, free from the judgements of our mind.
