Sundarakānda - Canto 13

Coming out of the aerial car, Puspaka, and not finding Sītā even on searching for her on all sides, Hanumān concludes her to have been killed. Believing that her untraceability, no matter whether it is reported to Śrī Rāma or not, may lead to disastrous consequences, Hanumān decides not to return to the mainland. Meanwhile, as he contemplates fasting till death or suicide or the killing of Rāvana, he catches sight of a grove which he does not remember to have seen and before proceeding to explore it mentally invokes the succour of Rsis and gods for success in his undertaking.
