Viraha is the pain of separation from the beloved. Devotional poetry, from the cowherd women longing for Kṛṣṇa to Mīrābāī, makes it a form of union: the more intense the longing, the closer the beloved. Sufi poetry knows the same theme as the reed’s lament for the reed-bed.
Viraha
Love in separation: the longing of the devotee for the absent beloved, a central mood of devotion.
