This text, structured in 24 tarangas (waves), systematically presents the theory and practice of mantra sastra, including bija mantras, yantras, nyasa, and dhyana. The dhyana mantras within it are used for invoking the presiding deities of various mantras and for attaining mental focus during sadhana. The dhyana mantra typically involves visualizing the vast expanse of mantras as a luminous ocean, with Mahidhara as the sage who churned this ocean.
The beej-akshara 'Om' is often central, representing the primordial sound from which all mantras arise. Phonetically, the mantra may include syllables like 'Hrim', 'Shrim', and 'Klim', which are associated with the Mahavidyas. The traditional purpose of chanting this dhyana mantra is to purify the mind, deepen one's understanding of mantra science, and ultimately achieve mantra siddhi (perfection).
It is recommended to be chanted during the brahma muhurta (early morning) or during specific nakshatras like Pushya or Ashlesha. The count is typically 108 repetitions using a rudraksha or sphatika mala. Ritual setting includes a clean, east-facing seat, with offerings of flowers and incense.
It is not recommended for those without a basic understanding of mantra shastra, as it is a gateway to deeper tantric practices. The *Devi Mahatmya* also underscores the importance of dhyana in mantra sadhana, aligning with the purpose of this dhyana mantra.
Salutations to the great ocean of mantras, with the seed syllables Hrīṃ, Śrīṃ, Klīṃ.
