। ॥ २५६ ॥
In plain words
Śiva Himself is directly the guru, and the guru is none other than Śiva in person. Seekers of liberation should never perceive even the slightest difference between the two.
Close to the Sanskrit
Śiva is indeed the guru directly; the guru is indeed Śiva Himself. Even the slightest difference of both should not be seen by seekers of liberation.
