Premanand Maharaj Ji
What does real sanyam (restraint) mean, and is outward control enough?
Restraint means never going against dharma
Do not go against dharma in any situation, and your restraint and contentment will be counted as successful. Controlling the tongue while the mind still enjoys the object is pretence.
So restraint means that in no circumstance should we go against dharma; then our restraint and contentment will be counted as successful.
