The Wasteland

1) Nietzsche's view point about superhuman and Eliot's theory about looking backward in past both are right apparently.
Nietzsche's view about "ubermensch" or superhuman is quite new and right on some point. That is good if one see possibilities of his own self and that helps him to grow so this idea is worth thinking.
On the other side Eliot says about looking backward in past. He took past mythologies in The Wasteland. Looking back and move forward in future with the help of past that is in one way helpful coz that mythologies helps one not to repeat that mistakes in future.
Nietzsche's theory is of  individual's growing but Eliot's one is mass growing theory.

2) Frued and Nietzsche both are the contemporaries but their background and field of working is different. Frued is believed in individuality and talk about "primitive instinct" where as Eliot believed in preservation of cultural traditions which means all together.
Frued was wrote that for progress of any individual primitive instinct was needed but in order to preserve tradition Eliot says that their is need for to grew together, for that example of Buddha was perhaps suitable.

3) In "The Wasteland" their are some lines which refers to Indian thoughts. Like,
"Ganga was sunken, and the limp leaves
Waited for rain, while the black clouds
Gathered far distant, over Himavant.
The jungle crouched, humped in silence.
Then spoke the thunder"
There is reference of Ganga which is Indian holly river and also himavant which means perhaps Himalaya. And also used Indian mythology here.

"DA
Datta:
what have we given?
My friend, blood shaking my heart
The awful daring of a moment's surrender
Which an age of prudence can never retract (such sacrifice are impusive and emotional, not based on prudence or calculations
By this, and this only, we have existed
Which is not to be found in our obituaries
Or in memories draped by the beneficent spider
Or under seals broken by the lean solicitor
In our empty rooms"
DA
Dayadhvam: I have heard the key
Turn in the door once and turn once only
We think of the key, each in his prison
Thinking of the key, each confirms a prison
Only at nightfall, aethereal rumours
Revive for a moment a broken Coriolanus
DA
Damyata: The boat responded
Gaily, to the hand expert with sail and oar
The sea was calm, your heart would have responded
Gaily, when invited, beating obedient
To controlling hands
These lines are taken from "Brihadaaranyak Upanishad" so that is Indian reference is there.
And last line of poem is also have Indian reference there,
"Shantih shantih shantih".
