Prakrteh kriyamanani gunaih karmani sarvashah
Ahankar-vimurdhatma kartaham iti manyate
                                                         Bhagvad Gita 3:27

(Under the influence of false ego one thinks himself to be the doer of activities, while in reality all the activities are carried out by nature as natural process)

Know the self to be sitting in the chariot, the body to be the chariot, the intellect the charioteer, and the mind the reins. The senses they call the horses, the objects of the senses their roads. When he (the Highest Self) is in union with the body, the senses, and the mind, then wise people call him the Enjoyer.

                                                                                                                                 Katha Upanishad, Third Valli

You cannot teach a child any more than you can grow a plant. All you can do is on the negative side - you can only help. It is a manifestation from within; it develops its own nature - you can only take away obstructions.

You have to grow from inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.

Yatha dipo nivatastho nengate sopama smrta
Yogino yatachittasya yunjato yogamatmanah

                                                                        Bhagwad Gita 6:19

(As a lamp in a windless place does not flicker, such is the disciplined mind of a Yogi practicing meditation on self).
