FORM - FORMLESS

Ashok Kumar : It is absolutely right. We all begin with form, but the aim is to transcend the duality of forms. Otherwise it becomes an obsession with form and impedes the journey. Thank you, my own Atman 

Meena Devi Dasi : Spirit is not formless but it is not like material form. No dualities. 
"He does not possess bodily form like that of an ordinary living entity. There is no difference between His body and His soul. He is absolute. All His senses are transcendental. Any one of His senses can perform the action of any other sense. Therefore, no one is greater than Him or equal to Him. His potencies are multifarious, and thus His deeds are automatically performed as a natural sequence." Śvetāśvatara Upaniṣad 6.7-8
"But realization of the Personality of Godhead, Kṛṣṇa, is realization of all the transcendental features: sat, cit and ānanda (being, knowledge, bliss) in complete vigraha (form)." Bhagavad-gita As It Is:introduction. 

Ashok Kumar : It is a deep subject, it has many interpretations. I don't quote the scriptures as they are also someone's concept. Krishna or Source is beyond form and formless. There is a abhang or bhajan of Sant Jnaneshwar; "Tuja sagun mhno ki nirgun re, sagun nirguna eku Govindu re."What I consider you, sagun or nirguna, the truth is you transcend both, You are the source. 
Ram Krishna paramhansa was a great devotee of Kaali. He was obsessed with the form of the Goddess. He was taught nirvikalpa samadhi by a great monastic sage Tota Puri. He was then able to transcend the form and dip in the ocean of bliss. The same thing happened with Sant Naamdev, a grea devotee of Lord Vithal (Krishna). The whole thing starte with devotion and ended in wisdom of the non-dual Reality. 

Meena Devi Dasi :  It is a very deep subject. Quoting here and there can be helpful, but ultimately it is a matter of personal realization. Who we hear from can help us. Who we associate with and how we associate is significant as we tend to take on their world view to one degree or another. Mostly people do associate with each other. Living completely alone in the forest or a cave is not so much practiced in these times. It is very difficult to even find such a forest or cave.
