Emotional activities create and sustain saṁskāras - emotional residues, or heaviness or grossness in our mind and consciousness.
They in turn make it difficult to act (think, speak, do) lightly and freely. In one way, it's like walking carrying two heavy suitcases. In another way, it's like walking along a path and constantly stepping off into a side track to investigate something related to that encountered on the path. Imagine doing this every few steps!
Primarily, physical or brain strain - excessive energy use, worry, etc. - comes from always, or even mostly, thinking, talking, and doing with others.
Especially comparing, analysing, judging - yourself with/against others, others with/against others.
Or relationships with others - making, breaking, changing, maintaining, quantifying, categorising, and so on.
Please note that others are necessary, and so are relationships with them.
One simple technique from the set is to hand over all the things causing worry and strain to someone, or something, inside you, which can, wants to, and does, support you.
Then you simply sit back (mentally), relax, and enjoy your life like a child or a baby!
Remember, though, that a baby learns, continuously, effort-less-ly, naturally.
But reaching this stage takes time and some degree of commitment to this handover.
Total commitment is called blind faith. It develops from an initial trust, experimentation and observation, seeing first if life can work at all with that handover, and then, whether it continues to work. If it does, trust becomes belief. Then, even in crises, if the handover stays, naturally, belief can become faith.
This doesn't mean zero brain or mind use. Just effective use, as needed than as habituated.
One still learns from the inspiration and observation of how situations work out with the insider in charge.
Planning and whatever else I learned about intellectual work must still occur.
Like implementing a plan, monitoring its progress, post-mortem analysis, and so on.
This tool is a continuous process, though mentally its usage range (or natural sequence) is never, seldom, occasional, frequent, constant.
There will still be times when I yank back emotional "control" due to habit or lack of trust or desire for the rush of energy from anger or other negative emotions. Or any other reason.
This is normal, and expected, as one moves from never to constant.
I simply hand over agency inward again, once I get back to a stable mental state.
Techniques from the Heartfulness/Sahaj Marg system are cyclical, and interconnected.
Thus, daily meditation helps in going deeper or subtler, and so cleaning away deeper or subtler saṁskāras.
Daily cleaning helps in meditating daily better - faster, longer, subtler - by removing surface emotions and emotional thoughts. And, daily meditation brings up more and more things to the surface.
Daily prayer helps in connecting inward, turning from outward. To, or with, that which is already within myself.
