What you say is quite true. A simple, straight and sincere call and aspiration from the heart is the one important thing and more essential and effective than capacities. Also to get the consciousness to turn inwards, not remain outward-going is of great importance—to arrive at the inner call, the inner experience, the inner Presence.
The help you ask will be with you. Let the aspiration grow and open the inner consciousness altogether.
