God is always God, the Absolute Truth is always the Absolute Truth
One can consider oneself Christian, Hindu, Jew, Muslim, Jain, Sikh, Zoroastrian or Buddhist but the Absolute Truth is always the Absolute Truth, regardless.
The Absolute Truth is "sat" or "that which is". In the material world we live in the "asat", in "that which is not". When we purify our intelligence, mind and senses, we always see God, the Absolute Truth. Many people talk about God or nirvana and may refer to it as "inside" . In the Absolute Truth, however, there is no difference between "inside" and "outside".
Theists understand that God has all qualities in unlimited quantities. God is complete and eternal. Some people don’t believe that God can be a person, because they understand themselves to have limited senses, and believe that if God is a person, he has to be limited as well. This is called anthropomorphism, a form of faulty reasoning.
While Buddhists are technically atheists, they do revere Buddha as their teacher, who was an incarnation of Vishnu. The appearance of Buddha is detailed in the 5000 year old Srimad Bhagavatam. This Vedic text describes the actions of Krishna, His appearances as well as His devotees.
A buddhist is someone who, according to the teachings of Buddha, renounces all kinds of worldly violence and temporary sensual pleasure in order to eventually reach nirvana. A devotee of Krishna attains nirvana, the cessation of all material activity, very easily because of re-establishing the eternal relationship with Krishna. Nirvana is not an absolute void. Nirvana means to become materially empty by becoming spiritually full.
In Bhagavad-Gita the word buddhi is used quite often, for instance in 10.8:
"Aham sarvasya prabhavo mattam sarvam pravartate iti matva bhajante mam budha bhava samanvita"
"I am the source of all spiritual and material worlds, everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts."
"Budha bhava samanvita"; those who have buddhi (understanding/knowledge), worship Krishna in knowledge, love and devotion. So they don’t worship a political party, a sectarian faith or their bank balance.
Being more or less exhausted materially is an important condition for re-establishing your relationship with Krishna. Krishna can of course help you with that, internally and externally. Your own desire is of great importance here. A strong desire for Krishna, God, the Absolute Truth, is the best desire you can have.
