He constantly strived to 'reach and teach' every student under his care. Such was the reputation of Muthannaval.
Muthannaval taught Prose, Poetry, Grammar, Kavyam, Natakam, Alankaram and Veda Sastram and Vedanta. In Vedic recitals the same verses in the Four Vedas were recited in four different ways as some alphabets or accents changed. The pronunciations for each of the prayers and texts for rituals are considered very important to gain full benefit of the rituals. A generalized standard method of recitation and pronunciation of Vedic texts were derived from the ancient times. Vedic prayers were generally recited in the same way over generations, from teacher to students following certain basic rules of pronunciations and grammar. These rules are given in the Vedas themselves and in certain texts referred to as Vedangas. Every day Muthannaval trained his students to do Rama Nama and Hari Nama Sankirthanam and Bhajans.
