Ye tvaksharamanirdeshyamavyaktam paryupasate
Sarvatragamachintyam cha kootasthamachalam dhruvam.

Te prapnuvanti mamev sarvabhoothite ratah.
Translation: -
Those who worship the unmanifested, the one who lies beyond the perception of the senses, the all pervading, inconceivable, unchanging, fixed and immovable ie the impersonal (without any from) conception of the absolute Truth-by controlling the various senses and who are equally disposed to everyone and are involved in the welfare of all, ultimately achieve Me.
Purport: -
In the previous text (taken in last issue) the supreme Lord Krishna said that the worshippers of His personal from are the most perfect yogis but in these texts he makes it clear that it is possible for the worshippers of unmanifest also to achieve God.
The aim of this kind of worship is given by using eight adjectives, which though sufficient are not complete in themselves because one of these adjectives 'Avyaktam' in itself says that he is beyond the perception of senses and hence can not be explained.
He tells Arjuna that the worshippers of absolute Truth in its impersonal from, are required to control their senses not only outwardly but also inwardly ie they should try that they are not attracted towards sense gratification...... Here one thing is worth mention that controlling senses is not considered a prerequisite for the worship of personal form of God. It is necessary for the worshipper of impersonal from and a Karmayogi.

He further describes the object of contemplation for the worshippers of impersonal from as the one who is not the subject of mind or thought as he is beyond this material world; who is all-pervading ie he is present everywhere, everytime, in all objects and forms; who can not be explained in any language or word; who is unchanging as trasience is the symptom of material world but the creator of it always remains the same; who remains fixed and immovable; who decan not be diminished or destroyed and who does not have any from or size. If a worshipper contemplates on such impersonal from of God he may achieve the knowledge of absolute Truth.

Such worshipper should also be involved in selfless service of all. For this he should be free of all desires, ego; attachments and possessiveness. He must considers that everything belongs to God and he, like a trustee, should utilize it in the welfare of all.
Using body to serve others kills his ego and using his material possessions in selflessly serving others kills his possessiveness. He detaches himself from his flase ego and not from the world. He thinks that his well being lies in the well being of all.
He remains equipoised in all circumstances and sees God in all. He might treat people and things in different ways in practical life according to their utility, from etc. but he does not fail to see the all pervading God in all.
If a worshipper fulfils the above mentioned conditions, he realizes the sameness of soul and the Supreme soul i.e. he knows that his real self is also described by same adjectives as supreme soul. He gets to self realization. ultimately he also achieves the same goal as the worshipper of personal from of God.
