The seeker may come to the correct conclusion that Knowledge is the surest way to Self Realization. Of all the methods prescribed by the scriptures, the Path of Knowledge (jnana yoga) is the surest and shortest means of Self Realization. You have all heard the message of Non-Duality and how the visible is not real. Having heard the message of Advaita from his Guru, the seeker comes to the correct conclusion that all that is visible or destructible or has attributes is unreal. What surprises the disciple is when the Guru encourages and endorses the worship of the God with attributes (saguna Brahman). In fact, the Guru says that worship and devotion to God, with or without attributes (saguna or nirguna) is a must even for the disciple who has Realized, to stay established in the Knowledge of Non-Duality.
Nothing is more superior to Knowledge as you know by now. The disciple wants to know why after having experienced the Truth, should one continue along the path of Worship (Bhakti). Having come to the realization that the Truth is without any attributes, why should one continue to worship that which has attributes? In fact, having attained the Ultimate Knowledge, why should one bother to pursue any spiritual practices at all, like worship of the Guru or God with attributes? Why should one with Knowledge of That which is without attributes (which is the Reality), bow down to an idol or photograph or an idol of a God or Guru and accept that which is unreal?
In a previous essay, this author has discussed about devotion after realization (please refer to that essay). Let it be clear, that there should be no doubt that the teachings of the Guru are the final authority. This is called faith and devotion to the Guru. Without this there is no hope for any seeker or disciple to attain Liberation.
Having said that, the seeker has a right to have his questions and doubts cleared. Now, please consider this carefully. Having acquired Knowledge and Realization, are you still doing things in life including your work, taking care of your family, their needs, your finances, your friends, and are you still participating in the activities of your family and society? Are you still eating meals, taking a bath, drinking water, cleaning the house, and taking care of your personal needs? If the answer is yes to all of the above questions, then why is it that you want to only exclude worship of the God with attributes? How come all other aspects of your life is accepted as real but not worship of the unreal God with attributes?
With your knowledge of discrimination, you know that all that is perceived is false, and yet you do not give up any of your activities. You listen to and obey the orders of your boss at work, which is the same as bowing down to the boss. So, why is it that you want to give up the worship of God with attributes? What is wrong with bowing down to the photograph of a God in human form or a Guru in human form or for that matter any form including one with multiple arms and legs, or with an elephant head? Please answer this question with sincerity. Has the mortal Guru who is one with attributes, not given you access to the Ultimate in Knowledge? Why then would you not want to bow down to this mortal Guru? What kind of knowledge is this?
One who has pride in attaining the Knowledge and feels " I am great" does not have the True Knowledge. He is one who is still identified with the body. Mind you, if there is no worship, there is no Knowledge (jnana). It is an indication of one who is still suffering from body-mind-identification. It is an identification of one who thinks "I am the doer".
So, never give up the worship of the Guru or the God with attributes. Start every action by remembering your God or Guru. Remember that God is the doer of all actions. By leaving all actions to a God with attributes, one slowly but surely becomes identified with That which is attribute-less and eventually realizes his True Nature, which is without any attributes whatsoever. May God bless you.
