We may not perceive what is within the range of the senses because we are:
“Disinterested or too far from.
Overly interested or too close to.
Blind or deaf to what is in front of us.
Distracted.
Not relating with what is there.
Seeing something between.
Letting something else dominate.
Confusing with something similar.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā Seven
