The Upanishads

I started reading the Upanishads again and this time I am understanding a few thing that it says.

Some nice points.

Katha:
Immersed in the abyss of ignorance, yet wise in their own ways, deluded fools go round and round, the blind led by the blind.

Most people are not privileged to speak about the Atman,
Lucky is he who knows about it,
Intelligent is he who seeks to understand it,
Blessed is he who studies about it from a Guru who speaks about it.

Isha:
Senses << mind << intellect << ego <<<< atman
Brahman is within and without. Do you see it?
