Shrila Bhaktisiddhant Saraswati Thakur writes in His commentary of Sri Caitanya Bhagavat (Antya Khand, Chapter 5, Text 357):
“Sri Nityananda Prabhu is directly svayamprakāsatattva. The holy name of the Lord and the Lord Himself combine together and manifest as svayamprakāsa Nityananda, the reservoir of transcendental happiness. Sri Nityananda Prabhu and the NAME SRI NITYANANDA are MOST RELISHABLE TRANSCENDENTAL OBJECTS.”
I don’t know about the form of Nitai (as I have never seen) but the form of Nitai’s syllables is truly a feast for the eyes.
Joy Doyal निताइ !
