The whole of spirituality is built around a single idea: ego death to liberate the spirit — pure, honest, meaningful, alive awareness. You can't commit ego suicide into nothingness; there must be something to replace it. Surrender must be practiced all the time, not just in the retreat of detached meditation. Live through meditation; surrender while you have an active mind. Let awareness live instead of the ego. Use the power of the spirit — don't keep it closed in a treasure box buried underground. Sometimes it is painful, but it's worth it. The ego can't love; it only expects reward. Better to keep yourself neutral until you realize how you have been loved all along. All other religious and spiritual stuff is mostly junk.
There's always something to surrender; something always stays in the way of going further. There are different depths in meditation. You can eat, talk, or do chores while simply being present. When you have the time and opportunity, always go as deep as possible. You must conquer the ego’s territory piece by piece. Even if it's just pacing back and forth, eventually awareness will win, because the ego is empty at its core.
