The Nighantu Dhyana Mantra is a meditative invocation directed toward the Nighantu, the ancient Vedic glossary traditionally attributed to the sage Yaska. The Nighantu itself is a collection of Vedic words grouped into three sections: naighantuka (synonyms), naigama (words occurring in the Vedas), and daivata (words related to deities). This dhyana mantra is chanted to invoke the blessings of Yaska and the goddess of speech, Vak, for deep comprehension of Vedic terminology and etymological insight. The mantra is not found in the Vedas themselves but is part of the auxiliary tradition of Vedanga, specifically the Nirukta, which is Yaska's commentary on the Nighantu. According to the Nirukta (1.1), the study of etymology (nirvacana) is essential for understanding the true meaning of Vedic mantras.
The dhyana mantra typically begins with an invocation to Yaska, such as "Om Yaskaya Namah," and may include the beejakshara "Aim," which is associated with Vak and Saraswati, representing knowledge and speech. The phoneme "Aim" is considered the seed syllable of the goddess of learning, and its repetition in the mantra aligns the chanter with the energy of divine wisdom. The traditional purpose of this mantra is to sharpen the intellect for Vedic study, to unlock the hidden meanings of Vedic words, and to gain proficiency in the science of etymology. It is believed that regular chanting bestows clarity of thought, memory retention, and the ability to discern the subtle nuances of Sanskrit. The recommended chanting context is during the Brahma Muhurta (early morning), facing east, after a bath and wearing clean clothes.
The count is typically 108 repetitions using a rudraksha or crystal mala. The ritual setting may include a small altar with an image of Yaska or a manuscript of the Nighantu, along with offerings of flowers and incense. Cautions: This mantra should be chanted with proper pronunciation and reverence, as it deals with sacred Vedic knowledge. It is advised to receive the mantra from a qualified guru and to maintain a sattvic lifestyle. The mantra is not for casual recitation but for sincere students of the Vedas.
