Bībhatsa and karuṇa-rasa are favorable for bhayānaka-rasa. Vīra, madhura, hāsya and raudra are unfavorable.
Purport
With the ecstasy of dread in devotional service a mixture of ghastliness or compassion is compatible. With the ecstasy of chivalry in devotional service a mixture of conjugal union, laughter or anger is always incompatible.

Commentary
Karuṇa-rasa nourishes fear by thinking of future separation from the lover and the consequent suffering. Vīra, madhura, hāsya and raudra-rasas are unfavorable for nourishing fear when manifested in the person experiencing fear.
