The Truth is to be realized here in this life. It is vain to expect that things will change and improve after death in worlds that are happier than ours. The change or improvement cannot come from outside of yourself. It has to be worked out by yourself from within yourself. The world you reach after the body is shed is determined by the level of consciousness reached while in the body.
Verbal knowledge is of no avail for the destruction of the delusion of the world.
Let no blind men be led by the blind. It is wisdom to go straight to the essence of the scriptures, like the swan sipping milk out of water. Study them, know their essential truth and then leave them aside like husk after collecting the grain. Remember, the body does not last for ever. Age prowls like a leopard, diseases strike like an enemy.
