What You Think You Become..
It is true....
This is pretty much true. Whatever you think constantly, you become that. And at the time of death, whatever you desire to become or wish you take that form in the next janma.
It is not as if simply, at the time of death you remember God and you will achieve moksha. It is the net result of your desires throughout your life. It is based on the law of karma. When you die your body is dead, but there is little intellect left. Now whatever you wish or desire, you take that form, which is known as rebirth.
However, if you are constantly a devotee of God, you will certainly achieve moksha. Depending however if you reach the state od realization.
In one of her previous speeches, Smt. Jaya Row said that ur whole focus (chetna) should be held btw. your eyebrows, with eyes lifting upwards. This pose at the time of death makes you achieve moksha. Sincerely speaking, it wasn't even clear to me too.
