Greater is their trouble whose minds are set on the Unmanifested; for, the goal – the Unmanifested – is very hard for the embodied to reach.
The embodied: Those who identify themselves with or attached to their bodies
(Dehabhimana).
Those who seek the Manifested Lord and those who seek the Unmanifested Lord reach the same goal. But the path taken up by the latter is arduous because the aspirant has to practise utmost self-control, renounce the world outwardly and inwardly, wipe out all human emotions and desires and still the mind in the contemplation of the Absolute. It is also extremely difficult to fix the restless mind on the formless and attributeless Self. Such a method of contemplation demands a sharp, one pointed and subtle intellect. The Immutable does not offer an easy hold to the mind and the path is more arduous.

For a majority of the seekers meditation upon The Lord as expressed in the Universe, a Personal God (manifested form) is easier because they have a tangible ideal of the Lord to whom they can direct their feelings, emotion, love, will, energies and knowledge.

WORSHIP OF THE QUALIFIED ASPECT OF THE LORD IS EASIER

Tesam, for them; avyakta-asakta-cetasam, who have their minds attached to the Unmanifest; klesah,the struggle; is adhika-tarah, greater. Although the trouble is certainly great for those who are engaged in works etc. for Me, still owing to the need of giving up self-identification with the body, it is greater in the case of those who accept the Immutable as the Self and who kept in view the supreme Reality. Hi, for; avyakta gatih, the Goal which is the Unmanifest-(the goal) which stands in the form of the Immutable; that is avapyate, attained; duhkham, with difficulty; dehavadbhih, by the embodied ones, by those who identify themselves with the body. Hence the struggle is greater. We shall speak later of the conduct of those who meditate on the Unmanifest.
