This mantra is dedicated to Lord Kṛṣṇa, the eigth incarnation of Viṣṇu. He is considered the most important incarnation, as he appeared in his true full form. He is also the one who offered the teachings of Bhagavad-gītā to his warrior student Arjuṇa. He also destroyed many demons who were an obstacle to the path of light. Meditating on him will not only drive away our own inner obstacles but also bring forth the light that is hidden in our heart.
Enjoy this mantra, by listening to it 8 times each time, and try to hear this about three times a day.
oṁ kṛṣṇāya namaḥ
