We should never be 'devotees' of anybody! We should never be 'disciples' of anybody! We should aim to become masters of ourselves! That is the goal.
People who have set their goal... 'Be A Master'... Must stop talking casually ! ... Must stop listening to others casually ! ... Must stop reading newspapers casually! ... Must stop watching TV casually! ... One should speak only when it is absolutely 'necessary'. Only when it is absolutely 'necessary' one should listen to others, Similarly, one should cease to think casually!.
Mastery' is easy for a regular sadhaka and difficult for an irregular sadhaka. So, regular practice and always being conscious of the goal, will make everything happen.
