भागवत - द्वंद्वम्

अविद्यमानोऽप्यवभाति हि द्वयो
    ध्यातुर्धिया स्वप्नमनोरथौ यथा ।
तत्कर्म संकल्पविकल्पकं मनो
    बुधो निरुन्ध्यादभयं ततः स्यात् ॥

- भागवत

avidyamAno api avabhAti hi dvayo
    dhyAtuH dhiyA svapna manorathau yathA ।
tat karma saMkalpa vikalpakam mano
    budho niruMdhyAd abhayam tataH syAt ॥

- bhAgavata

Even though there is only one truth, it may appear as many. Just like a person who sits to meditate sees dreams and wishes as separate even though they are the same. Hence one must contain the mind that thinks in both directions - positive and negative. Only then can one be free from fear.
