This saying makes me think about my own teachers in Silat Seni Gayong. I was taught first by Gene Scott, a senior student of Cikgu Sam, then taught by Joel Champ and finally Cikgu Sam took me as a student. At each point in training, someone new "appeared" to continue my journey. From my teachers in the United States, I have been able to learn from Cikgu Jaz, Cikgu Malik, Cikgu Kahar and many other Cikgu in Malaysia. Some of the teaching is not crossing hands but talking and explaining. This is also training.
Sometimes I ask questions that I am not ready to know the answers yet. Sometimes I am. Sometimes I get asked questions that students aren't ready to know the answers to.
All you can do is trust yourself and trust your Cikgus. Train hard and the teachers will appear, just don't forget to look for them!
