To keep something secret.
कुछ को गुप्त रखना। (Kuch ko gupt rakhna.)
"I’ll tell you a secret, but keep it under your hat."
"मैं तुम्हें एक राज़ बताऊँगा, लेकिन उसे गुप्त रखना।" (Main tumhe ek raaz bataunga, lekin **use gupt rakhna**.)
feeling very sure of yourself
to continue hoping even when it seems impossible
to face great difficulties with courage
Don’t surrender; keep trying even in difficult circumstances...
to make a brief appearance in a film
in the end, right will triumph over wrong
