Why are the experiences one undergoes in worldly life important for a spiritual aspirant?
Bhakti and shraddha (devotion and faith) are the two oars, with which you can take the boat across the sea of worldly life (samsara).
A child told its mother, when it went to bed at night, "Mother! Wake me up, when I get hungry." The mother answered, "There is no need. Your hunger will itself wake you."
So too, when the hunger for Him comes, it will itself activate you and make you seek the food you need.
He has endowed you with hunger and He supplies the food; He has endowed you with illness and He grows the specifics you need.
Your duty is to see that you get the proper hunger and the right illness and use the appropriate food or drug!
Man must be yoked to samsara (worldly life) and broken; that is the training, which will teach that the world is unreal; no amount of lectures will make you believe it is a snake unless you actually experience it.
Touch fire and get the sensation of burning; there is nothing like it to teach you that fire is to be avoided. Unless you touch it, you will be aware only of its light.
It is light and heat both; just as this world is both true and false, that is to say, unreal.
- Divine Discourse, Mahashivaratri, 1955.
More than the knowledge that you can get from reading the scriptures, you should value the wisdom that you can get from experience.
