How can one know if he is fit for the spiritual life before taking up Yoga?

Sri Aurobindo: How can anyone know before he puts his step on the path? He can only know whether he has the aspiration or not, whether he feels a call or not. You have said that to enter the path of Yoga “all one needs to know is whether the soul in one has been moved to the Yoga or not”. But how to know this clearly before entering the path?

There is behind all the vital nature in man his true vital being concealed and immobile which is quite different from the surface vital nature. The surface vital is narrow, ignorant, limited, full of obscure desires, passions, cravings, revolts, pleasures and pains, transient joys and griefs, exultations and depressions. The true vital being, on the contrary, is wide, vast, calm, strong, without limitations, firm and immovable, capable of all power, all knowledge, all Ananda.

Talks with Sri Aurobindo
Nirodbaran

Dr. M: How is it that some people lose at once their consciousness in meditation, and their body sways this side and that, even falls to the ground? Sri Aurobindo: That happens with many. And that is why some Yogis bind themselves to a support to prevent falling. The Yogis who practise asanas remain erect.

This world has a double aspect. It seems to be based on a material inconscience and an ignorant mind and life full of that inconscience: error and sorrow, death and suffering are the necessary consequences. But there is evidently too a partially successful endeavour and an imperfect growth towards Light, Knowledge, Truth, Good, Happiness, Harmony, Beauty, at least a partial flowering of these things.

"The Supreme is the Purushottama, eternal beyond all manifestation, infinite beyond all limitation by Time or Space or Causality or any of his numberless qualities and features. But this does not mean that in his supreme eternity he is unconnected with all that happens here, cut off from world and Nature, aloof from all these beings. He is the supreme ineffable Brahman, he is impersonal self, he is all personal existences.

On a dim ocean of subconscient life
A formless surface consciousness awoke:
A stream of thoughts and feelings came and went,
A foam of memories hardened and became
A bright crust of habitual sense and thought,
A seat of living personality
And recurrent habits mimicked permanence. Mind nascent laboured out a mutable form,
It built a mobile house on shifting sands,
A floating isle upon a bottomless sea.
A conscious being was by this labour made;
It looked around it on its difficult field
In the green wonderful and perilous earth;

The obscure mysterious creatrix ends indeed by delivering the secret consciousness out of its thick and tenebrous prison; but she delivers it slowly, little by little, in minute infinitesimal drops, in thin jets, in small vibrant concretions of energy and substance, of life, of mind, as if that were all she could get out through the crass obstacle, the dull reluctant medium of an inconscient stuff of existence.

Q&A on
Thoughts and Aphorisms

How to cooperate in the cure of the evil and the ugly that one sees everywhere ? By love ? What is the power of love? How can a phenomenon of individual consciousness act on the rest of mankind?

Mother: How to cooperate in the cure of the evil and the ugly?...
It can be said that there is a scale of hierarchy in collaboration or action : a negative cooperation and a positive cooperation.

THE INEVITABLE CHOICE

It was inevitable that in the course of the sadhana these inferior parts of the nature should be brought forward in order that like the rest of the being they may make the crucial choice and either accept or refuse transformation. My whole work depends upon this movement; it is the decisive ordeal of this Yoga. For the physical consciousness and the material life cannot change if this does not change.
