Types of Attachment to Self

We have attachments to self and to dharmas which create obstacles that prevent realization. Attachments are divided into two types:

1) Innate attachments are present at birth. They are subtle and exist in all sentient beings. Innate attachments are found in both the sixth and seventh consciousness'es. When the state of no outflows (enlightenment) is reached innate attachments are eliminated.

2) Distinguished attachments are learned. They are less subtleand more obvious than innate attachments and come from the distinction making process of the fifth and sixth consciousness'es.
