Sometimes we really make things far more complicated than they need to be. This also happens in relation to our practice.
Vajrayana can seem pretty complicated with all the deities visualised, music and so forth. This might discourage some people, but it needn't. The word practice implies a process of doing something and, hopefully, becoming more familiar with it. So when starting a new practice that seems difficult and elaborate, don't be discouraged, just take it at your own pace and soon it will flow without effort.
This is pre-retreat advice to myself.
