endeavor

a purposeful or industrious undertaking (especially one that requires effort or boldness); "he had doubts about the whole enterprise"

"यह है तुम्हारा बदला और तुम्हारा प्रयास क़द्र करने के योग्य है।"

The Hour is coming—but I keep it almost hidden—so that each soul will be paid for what it endeavors.
