The bats are the evil qualities of hate and malice and greed. (SSS Vol.7, p. 85)

To realise the Lord in every being, you must cultivate prema and drive out the bats that infest the dark caverns of your heart; the bats of hate, envy and malice. Let the light of prema illumine your thoughts, your words, your movements, your activities, your judgements (SSS Vol.4, p. 107)

The bats will be hanging to the branches of trees with their heads downwards. They move about in darkness only. Their entire life is spent in darkness. Is it anybody’s malice that makes the bats hang heads down from their perches on the branches? No, this is not anyone’s making. It is God’s leela. (SSS Vol.39, p. 220)

Bats fly in the sky like all other birds which perch on the branches of trees to take rest. However, unlike other birds, bats hang from the branches with their head down and feet up. Has anybody tied them in this manner with a thread? Or, has someone forcibly put their heads down? No. It is the result of their Karma. In the same way, if man harbours evil thoughts and performs evil actions, he is bound to get evil results. However, if he performs good actions, he will get good results in accordance with the nature of his actions. When we look at them, even bats appear to be like other birds. But, they have a different fate unlike other birds, which fly freely. (SSS Vol. 41, p. 40)
