Significance of Ū
In Māhēśvara Sūtras
In the māhēśvara sūtras, it is third in order and appears in the very first sūtra: “a-i-u-ṇ”. The place of articulation of ū is the “Lips” (oṣṭha). The sūtra “upūpadhmānīyānām oṣṭhau” states that the letter ‘ū’, along with the class of Pa (Pavarga, i.e, Pa, Pha, Ba, Bha, Ma) and upadhmānīya (Half visarga), is articulated by the lips. The letter ū in two mātrās period of pronunciation is Long (dīrgha) and in case of three mātrās period of pronunciation, it is treated as Very Long (Pluta). It can again be treated as three-fold on the basis of udātta (Acute), anudātta (Grave) and svarita (balanced). Considering the nasality and non-nasal quality, it is six-fold. Totally, it can be of 18 forms.
As it is stated in the śikṣā that “Svaras (Vowels) and ūṣman consonants are pronounced openly, the ū is pronounced openly and with inward effort. It is pronounced openly since there is no touch of the tip of the tongue and others. This too has been stated in the śikṣā as “the vowels are untouched and the śal consonants are partly touched”.
In Kāmadhenu Tantra
The kāmadhenu tantra states: “The ū has the form of the bent conch and is curved in shape. It is of the form of five prāṇas and represents the five gods. It represents the five prāṇas also the lightening, yellow. It represents the four ends of life, namely piety, wealth, desire and liberation. It awards happiness.
