I have been scrolling through one of Shreemati MahaLakshmi Tantra Paddhatis this week. One of the Chapters was about 108 Names of Shree MahaLakshmi.
But the end of the Chapter was quite unexpected because it contained The Mantra of Shreemati RangaNayaki-Devi.
The Mantra is simple, but very beautiful in its simplicity:
ॐ श्री रङ्गनायकी महालक्ष्म्यै नमः
OM shrI ra~NganAyakI mahAlakShmyai namaH
