Why a mantra is given so secretly; as a whisper

You know what psychology says, if there is anything in your mind that is bothering you, speak it out. Bring it to the field of expression. Then you are free of it.

We want the mantra to stay inside. We don’t want it to be in the field of expression. We want that mantra to remain in the mind and take the mind deeper. So for your mind to go deeper, you need to have a mantra which is not in the field of expression; which is secret. That is why it is given secretly. A secret stays deeper in your heart, deep in your consciousness.

So mantra is a vehicle for the mind to dwell deeper into the consciousness. That is why it needs to be given secretly. 
The mantra given to me may be a very open (common) mantra, but my mantra (the one given to me), I keep it a secret so that I can go deeper into meditation.

This is the idea from ancient times. It is so scientific. 

There are mahamantras that everybody can chant loudly. But a personal mantra is what one has to keep secret. That is what we give you in the meditation course, i.e., the Sahaj Mantra. You keep it to yourself and don’t bring it into the field of expression. But other mantras like ‘Om Namah Shivay’, and  'Om', these can be chanted loudly. They enhance the vibrations.

Dealing with constant blame, especially from a dear one

If someone constantly keeps blaming you, then do not care about it.
It happens so often, when mothers constantly blaming their children, the children stop caring about what their mother is saying. This is because they know she is going to continue the same behaviour every day, right?

The trouble happens when someone who never complains suddenly complains. When someone who is never rude suddenly becomes rude, that bothers you more, isn’t it so?

Either you are eternalizing the problem, or you lack the skill to deal with what is happening. These are the only two aspects to it. So skilfully handle these situations and do not eternalize them.

Everybody has a right to be a little imperfect. You should accept others’ imperfections and your own imperfections as well. When you do not accept peoples’ imperfections, you get angry. And when you do not accept your own imperfections you feel guilty and then you become angry at yourself. Both situations are not healthy and congenial for you. So, you need to keep a little space in life for imperfections, and just move on. Do not get stuck in the past.
