Book on deity worship needs help (ISKCON) ys pd

Hare Krsna Prabhus -- Pranams - Glories to Prabhupada, We are looking for Mother Silavati to help us in writing a book on sadhana bhakti -- Prabhupada refers to her in his letters, she, having written the first book on Deity Seva. Myself and a few others are in the process of writing a book on the complete process of sadhana bhakti as outlined in Prabhupadas instructions. If anyone out there can help us locate Mother Silavati,or that book, we would be greatly appreciative. thanks. damaghosa das
