Valmiki Ramayana Kishkindha Kanda Sarga 29 Shloka 20

चोदनादृते before prompting, कालः time, व्यतीतः elapsed न तावत् भवेत् cannot be used, चोदितस्य if he directs, कार्यस्य the task, कालव्यतिक्रमः time limit has elapsed, भवेत् will happen.

'Time will not be deemed lapsed in vain if the work is sincerely taken up without delay and without pressure from your ally, Rama. If it is undertaken under pressure, it will be considered transgression of time.
