From today, you must resolve to use your eyes properly, to see only the good. Why use binoculars to see distant objects? (SSS Vol.31, p.27)

Of what use are eyes that cannot see God?’ You use your eyes all your life to see the external world. What do you achieve thereby? No one attempts to see the Unseen. The daily chores are repeated endlessly---bathing and eating and sleeping. But there is no yearning to see the Unseen Divine. It is only when you develop that desire will your life become meaningful. It is that that will give you peace. (SSS Vol.17)

Develop the inward vision, taste the bliss it gives

So, you should endeavour to install Him in your heart and be ever aware that He is there. Radha alone had that consciousness and the uninterrupted Bliss derivable from that knowledge. Cultivate that knowledge, that closeness. When you are aware all the time, only of the body and its clamour for attention, how can you ever concentrate on the Dweller within? Develop the in-look, the inward vision, and taste the Bliss it gives, at least for half a minute every day; that will surely confer on you great strength and security. Radha prayed that Krishna must keep her in the cool shade of His Presence so that she might be saved from being scorched in the arid desert of earthly life. (SSS Vol.12)

Man cannot derive joy merely from things that are beautiful or from individuals who are beautiful. Man derives joy from the objects he loves and not from other things. It is the love that lends beauty to the object. Hence joy is equated with beauty and the sweetness of honey. Anyone who seeks joy should not go after things of beauty. The fountain-source of joy is within himself. To bring forth that joy man should cultivate the inward vision. (SSS Vol.22)

Today’s man, who claims to know everything and engages in exploring space, is unable to experience bliss. If one acquires the ability to explore the stars or walk on the moon, but is unable to understand his own true nature, he misses his integral consciousness. This consciousness is not related to knowledge of the external world. It can be experienced only by turning one s vision inward. Only when he has samagrata bhavam (integral awareness) will he have the fight perception of a sage. Only such integral vision can confer bliss. The greatest cause of bondage. (SSS Vol.25)

The practice of Dharma calls for the offering of all worldly desires to God and developing the inward vision.

Renouncing all Dharmas, take refuge in Me alone, says Krishna in the Gita (18:66). This implies that man must make it his primary aim to offer to God all external sensory, physical desires and cultivate spiritual thoughts centred on the eternal. (SSS Vol.26)

Man’s vision should not be confined solely to the external objects and worldly things which are transient and perishable. Man has been given this vision so that he may see the pure, sacred Divine consciousness abiding in his heart. The northward motion of the Sun, Uttarayana, is the appropriate occasion for developing this inward vision. This is the royal road for the spiritual aspirant to realise the Supreme. (SSS Vol.27)

Install the Divinity in your heart. As Krishna told Arjuna, make God sit in your heart, the inner chariot. There He is Mantra Swarupa, the form of sacred sound, and not yantra, which has no life force. Mantra is life. God is Mantra Swarupa and Hridayavasi (in-dweller in the heart). If you want to see God outside, your effort is an exercise in futility. Outward look is that of the animal. You should develop an inward vision. Then you can realise God. (SSS Vol.31)

If the eyes are open, we see the entire creation; and if the eyes are closed, we do not see anything of the creation. Thus, we conclude that this entire creation has come from our own vision. If there is vision, there is creation; and if there is no vision, there is no creation. Just as with extrovert vision we are able to see the external creation, so also with the help of  inward vision, we can see the inner self. This is what Krishna taught Arjuna. It was with a view to help Arjuna develop this inner vision, that the Lord had given him so many directions. (SSB 1976, p.139)

The spiritual aspirant (sadhaka) must first learn the secret of the ‘inward sight, the ‘vision directed inward’, and take his attention away from the exterior. You have heard so far little about the inner world, but divine life is nothing but this method of ‘inward living’. Just as the baby, after learning to watch and understands, tries to toddle here and there at home, so also the spiritual aspirant learns to toddle in the inner world and understands it. A healthy baby in the cradle waves its arms and legs in glee and lisps in joy, watching the lamp on the wall. Similarly, the spiritual aspirant, also healthy in body, mind, and soul, lying in the cradle of life, watches the inner world and claps the hands ceaselessly in great glee at that inner joy. This has to be done.

Besides, every thought, every word, every deed has to proceed from the full consciousness of knowledge. Direct your intelligence not to wander about but to dwell constantly in the inner world! This is the inward quest (antar vimarsha), and meditation (dhyana) is the most important instrument needed for this.

The spiritual aspirant can enter the inner quest (antar vimarsha) through the gate of self-examination. That gate accords welcome into the highest and holiest status possible in life to every aspirant who is endowed with humility and devotion. (DhyV, pp.24-25)

The truly wise say that one who knows God becomes God. As you perceive so you become. Therefore, when you gain integral vision, you take on the sacred nature of the divinity itself. To become a person of the highest wisdom, you must develop integral vision. You must steadily abide in the inner unity that is at the core of all the outer diversity. It is for this reason that Krishna commanded Arjuna to steadily turn his vision towards his highest self, and to maintain that vision at all times, under all circumstances. (SBGita)

The world you see around you is a creation of your own vision. Your vision should be used to see and realise the sacred Atma. This also means a change of external vision into internal vision. It is only when we can develop an inward vision that we will achieve detachment from the outward vision. (SSB 1977, p.234)
