Practice with Sincerity

This is a new phrase I learned from Master Sun Lu Tang.
Practice without sincerity ? I have to admit there were days
that's how I treated Tai Chi.

Tai Chi's rule past down is 3 rounds or 40 minutes at my fastest pace.
Sincerity pace ??

I did 40 minutes of cloud hands again yesterday.
I felt the pulsing. That's sincere practice.

I feel the needles or ants after 5 seconds of cloud hands.
But only in left hand.

I am really lazy

Just finished about 30 minutes of cloud hands.
The left hand of course felt more strange tinglings than the right hand.
This time, the wrist bone felt it, and then the tiger's mouth area
(also near thumb ),
then the ring fingers of both hands.

Heat was generated in the lower back muscles from the shifting weight from
one leg to the other. The warmth was stronger when I didn't shift as much weight
onto the knees. Staying more in the center, but I do shift some weight.
The heat did not go forward into the tan tien.

My wife again felt the heart beats in my left and right hands.
She first felt it in my palm in the area of tiger's mouth.
But this time, somehow I "exhaled" into the finger tips,
and she felt the "pulses" at the finger tips.

There was also, a little "cooling" feeling, not in the feet or legs like before,
but in the left arm.
I then opened the "kua" with Wing Chun stance.
Felt a very little tingling in the crouch area.

I am lazy. I should be doing this everyday.
