Yogācārabhūmi-śāstra, Volume 34 (Fifty-Nine)

Original text: 何以故。以彼犹有。能障现观粗品我慢。随入作意。间无间转。作是思惟。我于生死曾久流转。我于生死当复流转。我于涅槃当能趣入。我为涅槃修诸善法。我能观苦真实是苦。我能观集真实是集。我能观灭真实是灭。我能观道真实是道。我能观空真实是空。我观无愿真是无愿。我观无相真是无相。如是诸法是我所有。

Explanation: Why is it that one who deeply and earnestly dreads saṃsāra and aspires to nirvāṇa still cannot enter nirvāṇa, and cannot even fully comprehend and abide in the dharmas of nirvāṇa? It is because the practitioner still has coarse self-conceit (māna) that can obstruct direct contemplative realization (vipaśyanā). As the contemplative practice deepens, there arises mental engagement (manaskāra) that is either intermittent or uninterrupted, and the mind deliberates thus: "I have long been transmigrating through birth and death; I will continue to transmigrate through birth and death; I shall be able to enter nirvāṇa; I cultivate various wholesome dharmas for the sake of nirvāṇa; I can contemplate the truth of suffering and it is truly suffering; I can contemplate the truth of origination and it is truly origination; I can contemplate the truth of cessation and it is truly cessation; I can contemplate the truth of the path and it is truly the path; I can contemplate emptiness and it is truly emptiness; I contemplate wishlessness and it is truly wishlessness; I contemplate signlessness and it is truly signlessness. All such dharmas belong to me."
