Guru Gita
svadeśikasyaiva ca nāmcintanaṁ bhaved-anantasya śivasya cintanam || 33 ||
33. The chanting of one's Guru's name (nāmkīrtanam) becomes the chanting of the name of Śiva, who is ananta (the Infinite), and the meditation on the Guru's name (nāmcintanaṁ)—becomes the meditation on the Infinite Śiva.
