Historically, did the sanskrit varnamala contain two 'la' vyanjan varnas? It seems there was one in the 'ya' varga and another one in the 'sha' varga.
Current texts on sanskrit or hindi grammar and wikipedia show a varnamala with but one 'la'. However I have found differing configurations of the Rashi, Nakshatra and Kulakul chakras in different translations 1 2 of the Brhat Tantrasaara and also in blogs(https://shubhamalock.com/remedies/mantra-suitability/).
