Question on a Mahayana Sutra (Three Svabhavas)

First time trying this. Much Metta to all beings here. I've been studying and meditating on a Mahayana based sutra for months, which is quite detailed in philosophy. I don't seem to understand the meaning of a particular passage. "Now, Mahāmati, false discrimination rises from form (nimitta). How, Mahāmati, does it rise from form? In [the consideration of] the relativity aspect of Svabhāva, realities appear in various ways, as having forms, signs, and shapes; when, Mahāmati, these objects, forms, and signs are adhered to [as real], this adherence takes place in two ways. The Tathagatas, Arhats, and Fully-Enlightened Ones thus declare false discrimination to consist in attachment to names and attachment to objects. By the attachment to objects is meant, Mahāmati, to get attached to inner and external things [as realities]..." -Lankavatara Sutra, Chapter II, Suzuki Translation. I'm confused on what it means by attaching to objects as realities. Thoughts? Thank you!
