KathaUpanishad

ahma = Supreme Self or Reality;
yat = that is;
param titīrṣatām = of those who wish to cross;
abhayam = refuge;
pāram = far shore.
nāciketaṁ = that Naciketa Vidya;
śakemahi = may we master;
May we master that Nāciketa Vidya; which is bridge for those who sacrifice, and
which is the highest imperishable Brahman for those who wish to cross over and
take refuge in the far shore.
We are able to understand both, the Nachiketa fire which is the bridge of all sacrifices
(to cross misery) and also the highest, indestructible Brahman, fearless and the refuge
for those who wish to cross the ocean of Samsara.
We have the picture of a far away shore which is seperated from the present material
world, where the Supreme Spirit live.
The seperator is the ocean of Samsāra (Samsāra Sāgara). Each one of us, wishes to
find the way to reach the farther shore by either a ladder or a bridge. This metaphorical
"bridge” holds the worlds apart and also unites them. Now the Soul Self is the
bridge, the separating boundary for keeping these worlds apart. We build this
bridge by our choices in relation to the two worlds.
How can the Self (Man) build this bridge across the samsara to reach the destination?
Here is our problem. We are told that the Naciketa Vidya is the bridge that will take us
across the occean of Samsara. But no where in the Katha Upanishad this Vidya is
described. How is that the most essential step in the mission of mukthi was omitted
