The real spiritual progress of the aspirant is measured

 by the extent to which he achieves inner tranquility.

The harder the struggle, 

the more glorious the triumph. 

Self-realisation demands very great struggle.

Humility is not cowardice. 

Meekness is not weakness. 

Humility and meekness are indeed spiritual powers.

Put your heart, mind, and soul into even your smallest acts. 

This is the secret of success.
