Question: By constant sadhana, do you mean self-enquiry?

Annamalai Swami: Yes. By strength of practice, by doing this sadhana, this veil will be removed completely. There will be no
further hindrances. You can go to the top of Arunachala, but if you are not alert, if you are not paying attention, you may slip
and end up at Isanya Math [a Hindu institution at the base of the hill].
You have to make an enormous effort to realise the Self. It is very easy to stop on the way and fall back into ignorance. At any moment you can fall back. You have to make a strong determined effort to remain on the peak when you first reach it,
but eventually a time will come when you are fully established in the Self. When that happens, you cannot fall. You have reached your destination and no further efforts are required. Until that moment comes, constant sadhana is required.

Question: Is it important to have a Guru at this stage, this period when constant effort is required?

Annamalai Swami: Yes. The Guru guides you and tells you that what you have done is not enough. If you are filling a bucket with water, you can always add more if there is still space. But when it is completely full, full to overflowing, it is pointless to add even a single drop. You may think that you have done enough, and you may believe that your bucket is full, but the Guru is in a better position to see that there is still a space, and that more water needs to be added.
Don’t rely on your own judgement in this matter. The state you have reached may seem to be complete and final, but if the Guru says, ‘You need more sadhana ,’ trust him and carry on with your efforts.

Bhagavan often used to say, ‘The physical Guru is outside, telling you what to do and pushing you into the Self. The inner
Guru, the Self within, simultaneously pulls you towards itself.’

Once you have become established in the inner Guru, the Self, the distinction between Guru and disciple disappears. In that state you no longer need the help of any Guru. You are That, the Self.
Until the river reaches the ocean, it is obliged to keep on flowing, but when it arrives at the ocean, it becomes ocean and the flow stops. The water of the river originally came from the ocean. As it flows, it is merely making its way back to its source.

When you meditate or do sadhana, you are flowing back to the source from which you came. After you have reached that source,
you discover that everything that exists – world, Guru, mind – is one. No differences or distinctions arise there.

Non-duality is jnana\ duality is samsara. If you can give up duality, Brahman alone remains, and you know yourself to be that Brahman, but to make this discovery continuous meditation is required. Don’t allocate periods of time for this. Don’t regard it as something that you do when you sit with your eyes closed.
This meditation has to be continuous. Do it while you are eating, walking, and even talking. It has to be continued all the time.
