Dear Shankhadip,
Thank you for mentioning about the book here.
Coincidentally (or may be not), I have presently been reading this book "Ek Sonar Manush", since last few months, time and again. Every time I read this book it makes me spellbound and often dumb founded! So much intense and spontaneous spirituality - Swami Premeshanandaji and his words !
BTW, do you or does anyone can tell whether an english version of this book or atleast works of Swami Premeshananda-ji in english are available - that would be very helpful to all.
Holy mother was very much fond of the songs composed by Swami Premeshanandaji. When She used to stay at Jayarambati, She used to sing in her mind with closed lips, the beautiful compositions of his son, Premeshanandaji. One such composition is "Aaji kokil - kujone, Malay - Paban-e Shihori Uthiche Pran".
