Without giving up sloth, how can Truth be known? Without giving up passion, how can devotion take root? Be serene and calm in stress and storm - that is the Satwic or pious path to win the Lord, the Truth. The mind is a wonder, its antics are even more surprising. It has no distinct form or shape. It assumes the shape or form of what it is involved in. Wandering from wish to wish, flitting from one desire to another is its nature. It causes loss and grief, elation and depression. Its effects are both positive and negative. The mind will gather experiences and store them in the memory forever. It does not know the art of giving up! As a consequence, grief, anxiety and misery continue simmering in it. It is worthwhile to know the characteristics of your mind and the ways to master it, for you will ultimately benefit! Teach it sacrifice (tyaga), and you will become spiritually wise (yogi)!
If we see it in our own life, we wonder what is sloth, how did we experience it. And what about passion? In these words is the characteristics of the three gunas, but not just as principle, but the experience. We experience the stress and the storm and how it is to keep inside calm and in sathva to get to truth.
And we go on seeing the wandering mind and that we wonder about it and we also wonder why lots of people seem to have not even a feeling for the mind yet and the reason is, we don't listen enough, if we listen we have to get a feeling for it, because with his words it gets alive.
We can see in our inner vision the mind that it has not distinct form and shape and it takes the shape or form of our life and therefore, we always should see it in our life. It is in our life we have to face the patterns of a mind that experiences things and makes out a memory forever.
