I am accustomed to Biren’s1 handwriting, and can read it with little difficulty. But I am surprised at Tagore’s remark2 about the two years; he must have greatly misunderstood or misheard me.

Barin,3 but I had then a less ample view of the work to be done than I have now – and I am now more cautious about assigning dates than I was once.

In the planes in between where life has its word to say and things have to evolve under shock and stress, Time and Energy are too much in a flux and apt to kick against the rigour of a prefixed date or programme.
