हृदये चित्तसङ्घट्टाद्दृश्यस्वापदर्शनम्
In plain words
From the fusing of in the heart comes the seeing of what is seen and of sleep.

Śivasūtra with Kṣemarāja's Vimarśinī

In plain words
Through uniting the mind with the heart, the perceived and sleep are seen. This shining of all that is perceived as one, as the body, and of everything up to the void as what is perceived, which has just been described, is not hard to bring about. Rather: The heart is the light of consciousness, because it is the place where the universe stands. Through uniting the mind with it, that is, by contemplating it single-pointedly each time the mind moves, there is the seeing of the perceived, blue, the body, the prāṇa and the intellect, and of sleep, the void, which is their absence: they shine as they are, like one's own limb, the division of grasped and grasper given up. For the mind that enters into the light of consciousness sees the universe as wholly shot through with it. As the Vijñānabhairava says: "With the senses dissolved in the space of the heart, gone into the middle of the closed lotus, with the mind on nothing else, O blessed one, one attains supreme good fortune." For supreme good fortune here is the attainment of lordship over the universe. Of the great yogin who has reached the state of reality, the Svacchanda too says: "And he, in all beings, in things, tattvas and senses, in what is fixed and what moves, in the conscious and the unconscious, pervading the whole path, abides in oneness." In the Spanda, though, it is gathered up in just this line: "So, by resting in one's own Self, it will be so everywhere."
