I was asked what the yogic view of Christmas is. Firstly, Christmas is (like it or not), the remembrance of the birth of Jesus Christ. Everything else (the tree, the gift-giving, the partying) was added later.
The yoga system does not mention what is thought of today as ‘religions’. But it recognized eternal and universal spiritual truth/principals, which may be reflected within religions to different degrees.
But there was a significant focus on transcendentalists, and it was understood that transcendentalists were transcendentalists for all.
Here are the Vedic verses I quoted:
Even a moment’s association with a pure devotee cannot be compared to being transferred to heavenly planets or even merging into the Brahman effulgence in complete liberation. For living entities who are destined to give up the body and die, association with pure devotees is the highest benediction. – Bhāgavata Purāṇa 4.30.34
O my Lord! Transcendental poets and experts in spiritual science could not fully express their indebtedness to You, even if they were endowed with the prolonged lifetime of Brahmā, for You appear in two features—externally as the ācārya and internally as the Supersoul—to deliver the embodied living being by directing him how to come to You. – Bhāgavata Purāṇa 11.29.6
Therefore, O completely sinless ones, I ask you to kindly tell me what the supreme good is. After all, even half a moment’s association with pure devotees within this world of birth and death is a priceless treasure for any man. – Bhāgavata Purāṇa 11.2.30
One should know the ācārya as Myself and never disrespect him in any way. One should not envy him, thinking him an ordinary man, for he is the representative of all the demigods. – Bhāgavata Purāṇa 11.17.27
Just try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized soul can impart knowledge unto you because he has seen the truth. – Bhagavad-gītā 4.34
Stability is also attained by contemplation upon a saintly yogi whose mind is free from material desires. – Yoga Sūtra 1.37
