Rāja yoga, samādhi, unmanī, manonmanī, immortality, laya, tattva, void-not-void, supreme state…

This verse and the next list the many names for the same state of realization:

• Rāja yoga — Royal yoga, culmination of all practices
• Samādhi — Absorption, unification of the mind
• Unmanī — Beyond the mind, trans-mental
• Manonmanī — Mind without mind
• Amaratva — Immortality
• Laya — Dissolution, merging
• Tattva — Reality, essential truth
• Śūnyāśūnya — Void-not-void, neither empty nor full
• Paraṃ padam — The supreme state

Each term illuminates a different aspect:

• Unmanī emphasizes transcending the ordinary mind
• Laya emphasizes the dissolution of dualities
• Śūnyāśūnya describes a reality that is neither existence nor non-existence

The multiplicity of names suggests that the final state transcends any single description. Different traditions and temperaments emphasize different aspects of the ineffable.
